Microsoft's Hunt for a Topological Quantum Computer Qubit | NextBigFuture.com

Microsoft is developing Majorana-based topological quantum computer qubits which will be higher-quality and lower error rate qubits. A high-quality hybrid system made of InSb nanowires with epitaxial-grown Al shells has revealed ballistic superconductivity and quantized zero-bias conductance peak. This holds great promise for making the long-sought topological quantum qubits. Theorists have already begun designing solid-state qubits using the hypothesized quasiparticle. Researcher Pendharkar and his adviser, physicist Chris Palmstrøm of UCSB, say that it will likely be decades before anyone makes a topological qubit. The key advantage of Microsoft’s topological qubit is that fewer physical qubits are needed to make one
