Magic Quantum Code Surgery
Kathleen Chang, Anasuya Lyons, Yuanjie Ren +5
Non-Clifford operations required for universal quantum computation can be implemented by measuring logical Clifford operators. We present a generalized framework to fault-tolerantl…
Bias-preserving cat-cat CNOT gate via vacuum-conditional beam-splitter
Yufeng Ye, Connor T. Hann, Kyungjoo Noh +4
Cat qubits can exhibit strong noise bias due to their exponentially enhanced bit-flip times and only polynomially reduced phase-flip times with increasing photon number, which make…
When quantum thermal states look classical
Harald Putterman, Alexander Zlokapa, Jordan Cotler
At high temperature, quantum Gibbs states retain several classical features of the maximally mixed state: the absence of entanglement, the absence of magic, analyticity of the part…
Restrictions on non-Clifford fault tolerance and ruling out beyond-SQL quantum metrology
Constantin Cedillo Vayson de Pradenne, Ishaan Kannan, Harald Putterman +1
Quantum metrology promises a quadratic speedup over the standard quantum limit (SQL), but signal-aligned noise is expected to preclude this advantage in realistic settings. A poten…
Fault-tolerant quantum processing of physical experiments
Ishaan Kannan, Harald Putterman, Jordan Cotler
Quantum computers may reveal features of Nature inaccessible to conventional experiments, but manipulating raw quantum data introduces noise that degrades inference even when the p…
