Erasure surface code circuit without mid-circuit erasure checks
Margaret Pavlovich, Ivan Rojkov, Chen Wang +1
Quantum error correction (QEC) codes can correct twice as many erasure errors as Pauli errors. Because of this scaling advantage, there is significant interest in developing qubits…
Solving Constrained Optimization Problems Using Hybrid Qubit-Qumode Quantum Devices
Rishab Dutta, Brandon Allen, Chuzhi Xu +8
Variational Quantum Algorithms (VQAs) provide a promising framework for tackling complex optimization problems on near-term quantum hardware. Here, we demonstrate that hybrid qubit…
Hardware-Efficient Erasure Qubits With Superconducting Transmon Qutrits
Bao-Jie Liu, Ying-Ying Wang, Yu-Xin Wang +3
Quantum error correction using erasure qubits offers higher fault-tolerant thresholds and improved scaling by converting dominant physical errors into detectable erasures. In super…
Simulating electronic structure on bosonic quantum computers
Rishab Dutta, Nam P. Vu, Chuzhi Xu +7
Quantum harmonic oscillators, or qumodes, provide a promising and versatile framework for quantum computing. Unlike qubits, which are limited to two discrete levels, qumodes have a…
