Hybrid cat-transmon architecture for scalable, hardware-efficient quantum error correction
Connor T. Hann, Kyungjoo Noh, Harald Putterman +6
Dissipative cat qubits are a promising physical platform for quantum computing, since their large noise bias can enable more hardware-efficient quantum error correction. In this wo…
Preserving phase coherence and linearity in cat qubits with exponential bit-flip suppression
Harald Putterman, Kyungjoo Noh, Rishi N. Patel +17
Cat qubits, a type of bosonic qubit encoded in a harmonic oscillator, can exhibit an exponential noise bias against bit-flip errors with increasing mean photon number. Here, we foc…
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…
Efficient unitary designs and pseudorandom unitaries from permutations
Chi-Fang Chen, Adam Bouland, Fernando G. S. L. Brandão +3
In this work we give an efficient construction of unitary -designs using quantum gates, as well as an efficient construction of a parallel-secure pse…
Efficient Unitary T-designs from Random Sums
Chi-Fang Chen, Jordan Docter, Michelle Xu +2
Unitary -designs play an important role in quantum information, with diverse applications in quantum algorithms, benchmarking, tomography, and communication. Until now, the most…
