Stabilization of Kerr-cat qubits with quantum circuit refrigerator

Stabilization of Kerr-cat qubits with quantum circuit refrigerator

A quantum circuit refrigerator based on photon-assisted electron tunneling can effectively cool and stabilize Kerr-cat qubits by providing tunable dissipation while preserving their advantageous error-bias characteristics through quantum interference suppression of unwanted bit flips.

Universal validity of the second law of information thermodynamics

Universal validity of the second law of information thermodynamics

Scientists have proven that Maxwell’s Demon cannot violate the second law of thermodynamics in any quantum scenario, as the energy gains from information-based sorting must always be balanced by the energy costs of measurement and memory erasure, regardless of how these processes are implemented.
