Quantum Computing: A Game Changer
The advent of a quantum computer heralds a monumental shift, poised to revolutionize not just the tech industry, but also the realms of material science, medicine, and various manufacturing operations.
Defined as a device harnessing the distinctive properties of Superposition and Entanglement in quantum particles to perform computations, a quantum computer employs quantum bits, or qubits, as its foundational building blocks.
Superposition fundamentally amplifies information storage capabilities. Unlike traditional computers where a bit can only hold values of 1 or 0, a qubit has the potential to store an infinite array of values, amalgamating two distinct states. To illustrate, consider the analogy from my Rigetti article, likening a boat’s position to a superposition of its North and East coordinates.
Utilizing Dirac notation, a quantum superposition is represented as 0.41 /0> + 0.91 /1>.
Beyond Qubits: The Significance
While traditional computers operate on bits, such as the 6GB memory in my iPhone 14 amounting to 48,000,000,000 bits, this capacity proves insufficient for substantial scientific research. For perspective, a single strand of DNA demands 215 petabytes to store its information, equivalent to over 35,000 iPhones. In stark contrast, a solitary qubit can house an entire DNA strand, marking a paradigm shift.
Entanglement, the second pivotal quantum property, was once doubted by Einstein. This concept denotes the correlation between measurements of entangled quantum systems, rendering the states inseparable.
Detailed extensively in my IonQ article, entanglement endows two particles with a twin-like relationship, where the measurement of one particle instantly determines the properties of the other. This intrinsic quality forms the bedrock of quantum computer programming.
Quantum Computing: A Historical Context
The foundational properties of entanglement and superposition paved the way for the nascent realm of quantum computing. In the early 1980s, this domain was labeled computability and constituted obligatory coursework during my undergraduate mathematics studies. Researchers embarked on exploring potential algorithms for future quantum computers, an academic pursuit as the realization of building such computers seemed inconceivable at the time, known then as Turing machines rather than quantum computers.
An algorithm comprises a sequence of discrete operations to be executed on one or more qubits, housing information as they evolve in response to these operations. In quantum computing, these operations are referred to as gates, represented mathematically by matrices. The Hadamard operator, a quintessential operation, exemplifies this, transforming the measurement 0 /0> + 1 /1> to 1 /0> + 0 /1>, a concept integral to subsequent discussions.
In 1994, Peter Shor formulated an algorithm capable of swiftly factorizing large numbers into prime factors. For instance, deducing that 330 comprises 2x3x5x11, a seemingly intricate task, becomes trivial for classical computers. Conversely, factoring colossal numbers constructed from immense prime numbers is deemed insurmountable for conventional computers owing to the exponential time required.
Factorizing large numbers is pivotal in securing online financial transactions. When you input your credit card details on a website, the security hinges on large prime numbers, reliant on the one-way hardness concept. Shor’s algorithm notably undermines the complexity, jeopardizing the security of internet finance.
Shor’s seminal algorithm showcased the ability of quantum gate computing to tackle problems beyond the reach of traditional computers, signifying a watershed moment in the realm of quantum computing.
The Quantum Computing Conundrum: An In-depth Analysis of Current Realities and Future Prospects
Since the inception of the concept of quantum computing, there has been an explosion of mathematical work aimed at finding the algorithms needed to solve seemingly intractable problems.
The Definition of a Quantum Computer
A quantum computer must contain a system of qubits, all distinct from each other. These qubits must be able to hold an initial value or state and undergo a sequence of operations (gates) both individually and simultaneously using entanglement. Finally, the quantum computer needs to be able to measure the new state of the qubits and report its findings without error.
However, despite prolonged research, no computer has yet been developed to pass the necessary tests for a quantum computer. The current era is dominated by noisy quantum computers, much like the error-prone machines from the early days of computing in the 1950s.
Potential Architectures and Intractable Challenges
The potential architectures for constructing a quantum computer are numerous, and many companies and universities are researching various methods. However, numerous challenges persist in this pursuit.
- Is it Turing complete?
- Does it exhibit fidelity?
- Is it scalable?
- Can it maintain coherence?
- How many operations can be implemented before coherence breaks down?
Despite decades of research, nobody has yet succeeded in developing a computer that passes these fundamental tests.
Main Approaches to Building a Quantum Computer
The key to building a quantum computer lies in the qubits, which can exhibit superposition and entanglement properties. Current research encompasses various methods, such as nuclear magnetic resonance, neutral atoms, photonics, and even the exploitation of nitrogen-vacancy centers in diamonds.
The Superconducting Qubit Brigade
Many prominent quantum computing companies are endeavoring to build their machines using superconducting qubits, including Alphabet (GOOG), International Business Machines (IBM), Rigetti, and Baidu.
While the formation of an effective qubit that exhibits superposition and entanglement is possible, this approach is plagued by errors, requiring the superconducting qubit to be cooled to a temperature below 10mK, shielded from external influences, and still falling short in terms of coherence and scalability. Current superconducting computers struggle to make substantial progress and have failed to live up to independent analyses of their performance.
For instance, Google’s proclamation of achieving quantum supremacy in 2020 was swiftly challenged by IBM, and IBM’s 127 qubit computer’s performance was subsequently demonstrated to be replicable on a classical computer, indicating no enhancement over existing technology.
Trapped Ion Qubits
Companies like D-Wave and IONQ are exploring trapped ion qubits, leveraging lasers to ionize atoms and trap them in electrical fields. While these devices do not require extreme cooling and can operate at room temperature, the number of qubits in these systems is currently insufficient to harness the desired computing power.
D-Wave, for instance, has developed an annealing computer for optimization problems but falls short in terms of qubit addressability. On the other hand, IONQ is making progress, with its AQ35 system aiming for quantum supremacy, although skepticism persists given the recent track record of unverified claims in this arena.
The scientific community’s consensus dictates that a useful error-corrected quantum computer will necessitate a million qubits, a far cry from the current capabilities.
Microsoft and Topological Qubits
MSFT has been investigating topological qubits, vouching for a different approach to quantum computing.
Major Breakthrough Puts MSFT on Path to Quantum Computing Power
For decades, the pursuit of a fault-tolerant quantum computer has been riddled with challenges. Each method previously explored has been deemed unscalable in an error-corrected state. Undeterred, Microsoft, in a bold move, focused its attention on the theoretical field of topological qubits. The tech giant has recently announced a momentous scientific breakthrough that could lead to a quantum leap in computing power.
Revolutionary Anyons
Topological Quantum computers seek to harness the behavior of quasi-particles known as anyons. These exotic particles display non-trivial statistical behavior abstracted from local geometric detail, rendering them resilient to their surroundings and equipped with built-in error protection. However, these anyons only exist in 2-dimensional spaces, making them elusive in the 3-dimensional world. The most experimentally accessible anyon, the Majorana Zero Mode (MZM), found in condensed matter superconductors, provides resilience to errors due to an energy gap that separates its energy state from the rest of the spectrum. This unique characteristic grants MZM qubits hardware-protected coherence, a significant advantage that Microsoft could leverage for a quantum leap in share price performance.
Theoretical Framework: The Mathematics of Topology
In the 2-dimensional world of MZM anyons, a topological path around one anyon differs from a path around two anyons. This distinction, arising from the inability to transform one path into the other without passing through an anyon, underpins the storage of information and the development of topological entanglement. The braided nature of anyons allows for the operations required to perform quantum gates, furnishing added error protection due to the system’s topology remaining unaffected by small perturbations—an advantage not found in other systems.
Majorana Qubit: A Quantum Leap in Progress
To form a functional qubit, two superconducting nanowires with four MZMs are essential, with the addition of a third wire enabling gate operations and the potential for a quantum supercomputer. Microsoft’s successful realization of this development would mark the next significant step after a recent scientific breakthrough.
Microsoft’s Pioneering Scientific Progress
The Azure Quantum team has engineered devices capable of inducing a topological phase of matter bookended by a pair of Majorana zero modes. These quantum excitations, not naturally occurring, must be coaxed into appearing under incredibly precise conditions.
In a groundbreaking step towards developing an error-corrected supercomputer, further published work in 2023 showcased Microsoft’s successful engineering of an MZM anyon that passed the topological gap protocol—an essential milestone on the path to a fault-tolerant quantum supercomputer.
Although Microsoft has demonstrated its capability to create and control Majorana Zero Modes, there is still a long road ahead according to the company’s roadmap which comprises six significant steps. While a specific timeframe is not provided, it is evident that quantum computing has the potential to become a significant revenue generator for Microsoft well before the advent of the first quantum supercomputer.
Advance Notice on Azure Quantum Elements
In June 2023, Microsoft announced the preview of Azure Quantum elements, featuring the integration of the latest High Performance Computing (HPC) artificial intelligence and currently available Quantum computing, the addition of Co-Pilot to Azure Quantum—providing a natural language interface for writing code and running quantum simulations—and the outlining of Microsoft’s roadmap towards a quantum supercomputer.
As Microsoft continues to pave the way, it is evident that the pursuit of quantum computing, once a mere abstraction, is now firmly anchored in reality, poised to revolutionize the future of technology.

Moreover, the use of quantum computers is not a prerequisite, as Microsoft offers a simulation that operates on classical computers. This simulation, despite its lack of quantum computers, has proven to be remarkably powerful, leveraging quantum gate computing to an astonishing degree.
HPC, AI, and Quantum Computer Programming Results
On January 9th, Microsoft released a press release detailing a recent experiment by its Quantum team to develop a new battery material. The Azure system utilized AI chemical simulations to screen over 30 million candidate materials, eventually narrowing down to 500,000 potential candidates. Subsequent rounds of AI-based screening and traditional force calculations culminated in the identification of 20 promising candidates. Eventually, a breakthrough was achieved in the synthesis of a battery electrolyte using 70% less lithium than existing batteries.
The efficacy of Azure Quantum and its integration with AI has become evident. The Azure co-pilot simplifies the task of writing quantum gate computing code and has proven to be an invaluable tool, especially in the absence of quantum computing hardware.
Furthermore, revenue from Microsoft’s server products and cloud services has seen a 22% increase, driven primarily by the exceptional growth of Azure and other cloud services.
