Bias-preserving cat-cat CNOT gate via vacuum-conditional beam-splitter
Yufeng Ye, Yufeng, Ye +6
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…
Efficient Magic State Cultivation on the Surface Code
Yotam Vaknin, Shoham Jacoby, Arne Grimsmo +1
Magic state cultivation is a leading approach for generating the resource states required for fault-tolerant quantum computation. Here we present a new cultivation protocol that in…
Self-correcting GKP qubit and gates in a driven-dissipative circuit
Frederik Nathan, Liam O'Brien, Kyungjoo Noh +4
We show that a self-correcting GKP qubit can be realized with a high-impedance LC circuit coupled to a resistor and a Josephson junction via a controllable switch. When activating…
Magic State Injection with Erasure Qubits
Shoham Jacoby, Yotam Vaknin, Alex Retzker +1
Erasure qubits constitute a promising approach for tackling the daunting resources required for fault-tolerant quantum computing. By heralding erasure errors, both the error-correc…
Hardware-efficient quantum error correction via concatenated bosonic qubits
Harald Putterman, Kyungjoo Noh, Connor T. Hann +118
In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many…
