Glossary of Key Terms

Bit: The fundamental unit of information in classical computing, representing either a 0 or a 1.
Qubit (Quantum Bit): The fundamental unit of information in quantum computing, which can exist in a state of 0, 1, or a superposition of both.
Superposition: A quantum mechanical property that allows a qubit to be in a combination of multiple states simultaneously.
Entanglement: A quantum phenomenon where the states of two or more qubits become linked, regardless of the physical distance between them.
Decoherence: The loss of quantum properties (like superposition and entanglement) in a qubit due to interaction with its environment, leading to errors.
Quantum Error Correction: Techniques used to detect and correct errors in quantum computations caused by decoherence and other noise.
Topology: A branch of mathematics studying properties of geometric objects that are preserved under continuous deformations (like stretching or bending).
Topological Quantum Computing: An approach to quantum computing that aims to store quantum information in topological properties of a system to make qubits more resistant to errors.
Majorana Fermion: A theoretical particle that is its own antiparticle.
Majorana Zero Mode (MZM): A quasiparticle excitation predicted to emerge in certain superconducting systems, often at boundaries or defects, which behaves like a Majorana fermion.
Topological Superconductor: A type of superconductor that can host Majorana zero modes at its boundaries or defects.
Topoconductor: A term used by Microsoft for their specially engineered topological superconductor material.
Non-Abelian Anyons: Quasiparticles whose exchange (braiding) results in a non-commutative transformation of the system's quantum state. Majorana zero modes are an example.
Braiding: The process of physically exchanging the positions of non-Abelian anyons, used in topological quantum computing to perform quantum gates.
Parity: In the context of Majorana qubits, this refers to whether a pair of Majorana zero modes collectively corresponds to an even or odd number of electrons, encoding the qubit's state.
Tetron: A specific architecture for a single topological qubit used by Microsoft, typically involving a pair of nanowires hosting Majorana zero modes.
Measurement-Based Control: A method of manipulating qubit states by performing measurements, used by Microsoft in their topological qubit experiments.
Fault-Tolerant Quantum Computing (FTP): Building quantum computers that can reliably perform calculations despite the presence of errors.
Station Q: Microsoft's primary research lab and effort focused on topological quantum computing.
Majorana 1: Microsoft's announced Quantum Processing Unit (QPU) claimed to be powered by topological qubits.
DARPA US2QC Program: A Defense Advanced Research Projects Agency program focused on developing utility-scale quantum computing in a faster timeframe.
Post-Quantum Cryptography (Quantum-Resistant Cryptography): Encryption algorithms designed to be secure against attacks by future large-scale quantum computers.
