Constructing quantum codes from any classical code and their embedding in ground space of local Hamiltonians
Ramis Movassagh, Yingkai Ouyang
Implementing robust quantum error correction (QEC) is imperative for harnessing the promise of quantum technologies. We introduce a framework that takes {\it any} classical code an…
Avoiding coherent errors with rotated concatenated stabilizer codes
Yingkai Ouyang
Coherent errors, which arise from collective couplings, are a dominant form of noise in many realistic quantum systems, and are more damaging than oft considered stochastic errors.…
Trade-offs on number and phase shift resilience in bosonic quantum codes
Yingkai Ouyang, Earl T. Campbell
Quantum codes typically rely on large numbers of degrees of freedom to achieve low error rates. However each additional degree of freedom introduces a new set of error mechanisms.…
Describing quantum metrology with erasure errors using weight distributions of classical codes
Yingkai Ouyang, Narayanan Rengaswamy
Quantum sensors are expected to be a prominent use-case of quantum technologies, but in practice, noise easily degrades their performance. Quantum sensors can for instance be affli…
Quantifying quantum speedups: improved classical simulation from tighter magic monotones
James R. Seddon, Bartosz Regula, Hakop Pashayan +2
Consumption of magic states promotes the stabilizer model of computation to universal quantum computation. Here, we propose three different classical algorithms for simulating such…
Linear programming bounds for quantum amplitude damping codes
Yingkai Ouyang, Ching-Yi Lai
Given that approximate quantum error-correcting (AQEC) codes have a potentially better performance than perfect quantum error correction codes, it is pertinent to quantify their pe…
