Co-Designing Error Mitigation and Error Detection for Logical Qubits
Rohan S. Kumar, Takahiro Tsunoda, Sophia H. Xue +3
Near-term quantum workloads demand error management, yet the two lightest-weight techniques, Quantum Error Detection (QED) and Probabilistic Error Cancellation (PEC), have compleme…
Efficient Routing of Quantum LDPC Codes on Programmable 2D Toric Architectures
Kun Liu, Takahiro Tsunoda, Sophia H. Xue +5
Quantum low-density parity-check codes are promising candidates towards scalable fault-tolerant quantum computation. Among these, bivariate bicycle (BB) codes offer superior encodi…
Hybrid Oscillator-Qubit Quantum Processors: Instruction Set Architectures, Abstract Machine Models, and Applications
Yuan Liu, Shraddha Singh, Kevin C. Smith +11
Quantum computing with discrete variable (DV, qubit) hardware is approaching the large scales necessary for computations beyond the reach of classical computers. However, important…
A mid-circuit erasure check on a dual-rail cavity qubit using the joint-photon number-splitting regime of circuit QED
Stijn J. de Graaf, Sophia H. Xue, Benjamin J. Chapman +8
Quantum control of a linear oscillator using a static dispersive coupling to a nonlinear ancilla underpins a wide variety of experiments in circuit QED. Extending this control to m…
