In-Situ Simultaneous Magic State Injection on Arbitrary CSS qLDPC Codes
Kun Liu, Shifan Xu, Tomas Jochym-O'Connor +3
Quantum low-density parity-check (qLDPC) codes can encode many logical qubits within a single code block at low physical qubit overhead, yet magic state injection into such codes r…
Constant-Time Surgery on 2D Hypergraph Product Codes with Near-Constant Space Overhead
Kathleen Chang, Zhiyang He, Theodore J. Yoder +2
Generalized code surgery is a versatile and low-overhead technique for performing fault-tolerant computation on quantum low-density parity-check (qLDPC) codes. In many settings, su…
Universal adapters between quantum LDPC codes
Esha Swaroop, Tomas Jochym-O'Connor, Theodore J. Yoder
We propose the repetition code adapter as a way to perform joint logical Pauli measurements within a quantum low-density parity check (LDPC) codeblock or between separate such code…
Entanglement sharing across a damping-dephasing channel
Vikesh Siddhu, Dina Abdelhadi, Tomas Jochym-O'Connor +1
Entanglement distillation is a fundamental information processing task whose implementation is key to quantum communication and modular quantum computing. Noise experienced by such…
Adaptive Channel Reshaping for Improved Entanglement Distillation
Dina Abdelhadi, Tomas Jochym-O'Connor, Vikesh Siddhu +1
Quantum communication and computation heavily rely on entanglement distillation protocols. There is a plethora of distillation protocols for Pauli channels and also for some non-Pa…
Phase diagram of the three-dimensional subsystem toric code
Yaodong Li, C. W. von Keyserlingk, Guanyu Zhu +1
Subsystem quantum error-correcting codes typically involve measuring a sequence of non-commuting parity check operators. They can sometimes exhibit greater fault-tolerance than con…
