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…
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…
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…
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…
Simulating Chemistry on Bosonic Quantum Devices
Rishab Dutta, Delmar G. A. Cabral, Ningyi Lyu +23
Bosonic quantum devices offer a novel approach to realize quantum computations, where the quantum two-level system (qubit) is replaced with the quantum (an)harmonic oscillator (qum…
Holographic Gaussian Boson Sampling with Matrix Product States on 3D cQED Processors
Ningyi Lyu, Paul Bergold, Micheline B. Soley +2
We introduce quantum circuits for simulations of multi-mode state-vectors on 3D cQED processors, using matrix product state representations. The circuits are demonstrated as applie…
