Majorana 1

Majorana 1 is a hardware device developed by <a href="/facts/Microsoft_Azure_Quantum/DKldgMTf">Microsoft</a>, with potential applications to <a href="/facts/Quantum_computing/nbbcgmvq">quantum computing</a>. It is the first device produced by <a href="/facts/Microsoft/nGIDDXdx">Microsoft</a> intended for use in quantum computing. It is an <a href="/facts/Indium_arsenide/GMhtPVbU">indium arsenide</a>-<a href="/facts/Aluminium/7wmR8jYE">aluminium</a> hybrid device that admits <a href="/facts/Superconductivity/pqQAlSzJ">superconductivity</a> at low temperatures. Microsoft claims that it shows some signals of hosting boundary <a href="/facts/Majorana_zero_mode/39gzL0Nv">Majorana zero modes</a>.[non-primary source needed] The device can fit eight qubits. Majorana zero modes, if confirmed, could have potential application to making <a href="/facts/Topological_qubit/paJBK88q">topological qubits</a>, and eventually a large-scale <a href="/facts/Topological_quantum_computer/paJBK88q">topological quantum computers</a>.[unreliable source?] 
In its February 2025 announcement, Microsoft claimed that the Majorana 1 represents progress in its long-running project to create a quantum computer based on topological <a href="/facts/Qubit/WveeEubw">qubits</a>.[unreliable source] The announcement has generated both excitement and skepticism within the scientific community, in the absence of definitive public evidence that the Majorana 1 device exhibits Majorana zero modes.
