QuTech demonstrates real-time readout for Majoranas

Researchers at QuTech have demonstrated a fast, single-shot readout of fermionic parity, the non-local quantity that carries information in Majorana-based qubits. This capability is an essential step toward operating Majorana modes as qubits, because it enables initialisation and real-time tracking of the encoded state in a qubit-style device geometry. By establishing direct parity readout, ...
