Microsoft Azure Quantum is a public cloud computing platform that provides access to quantum hardware and software.[1][2] The platform includes multiple quantum hardware modalities such as trapped ion, neutral atom, and superconducting systems.[3]

Azure Quantum Elements software uses AI, high-performance computing and quantum processors to run molecular simulations and calculations in computational chemistry and materials science.[3]

Microsoft is developing a topological quantum computer based on Majorana zero modes.[4][1]

History

In 2000, physicist Alexei Kitaev proposed using Majorana particles for topological quantum computing.[5][6]

Michael Freedman and Kitaev authored a paper in 2002 demonstrating how a topological quantum computer could perform any computation that a conventional quantum computer could.[7]

In 2005, Sankar Das Sarma, Freedman and Chetan Nayak proposed creating a topological qubit using the fractional quantum Hall effect.[8]

In 2006 and 2008, Sarma, Freedman and Nayak developed theoretical proposals for topological quantum computing based on non-abelian anyons.[9][10]

In 2015, Microsoft developed its theoretical framework of Majorana zero modes for information processing through braiding-based topological quantum computing.[11]

Microsoft released Q#, a programming language for quantum algorithms in 2017.[1]

Azure Quantum was officially released for public preview in 2021.[1]

In 2023, Azure Quantum researchers found evidence consistent with the creation and control of Majorana quasiparticles for topological quantum computing.[12][4]

In 2024, Microsoft created 4 logical qubits from 30 physical qubits, demonstrating resilient quantum computing with reliable logical qubits while reducing the logical error rate by 800x compared to the physical error rate.[13]

Hardware

Microsoft is developing a topological quantum computer with qubits that are inherently resistant to error. The approach is based on Majorana quasiparticles, which act as their own antiparticle and have a charge and energy equal to zero, making qubits that are more resilient to disturbances.[3][4]

In 2023, Microsoft introduced three levels of implementation for quantum computing: Foundational (noisy physical qubits), Resilient (reliable logical qubits), and Scale (quantum supercomputers).[3][14]

In 2024, Microsoft developed a qubit virtualization system that used active syndrome extraction to complete over 14,000 error-free experiments on a trapped ion quantum computer. Improving upon the physical error rate by 800 times, the quantum error correction technique created 4 reliable logical qubits from 30 physical qubits.[13]

Later that year, Photonic and Microsoft performed a teleported CNOT gate between qubits physically separated by 40 meters, confirming remote quantum entanglement between T-centers - a first requirement for long-distance quantum communication.[15]

Software

In 2021, Azure Quantum developed Q# (pronounced Q Sharp), a quantum programming language, and an open-source quantum development kit for algorithm development and simulation.[1]

The Azure Quantum Resource Estimator estimates resources required to execute a given quantum algorithm on a fault-tolerant quantum computer.[16]

In 2023, Azure Quantum Elements added Copilot, a GPT-4 based large language model tool to query and visualize data, write code, and initiate simulations.[3]

The same year, Microsoft developed Quantum Intermediate Representation (QIR) from LLVM as a common interface between programming languages and target quantum processors.[17]

Benchmarking

In 2023, Microsoft introduced a benchmark for quantum computer performance called reliable Quantum Operations Per Second [rQOPS], which combines three metrics: logical error rates, clock speed and a number of reliable qubits.[14]

rQOPS is calculated as rQOPS=Q x f, at a corresponding logical error rate pL., where Q is the number of logical qubits and f is the logical clock speed.[14]
