摘要:

量子计算机有潜力高效模拟纳米级核磁共振系统动力学。本文展示噪声中间尺度量子计算机可用于模拟和预测纳米级核磁共振共振。为最小化所需门保真度,我们提出一种超导专用协同设计量子处理器,通过可调耦合器将transmon量子比特电容耦合到中央共面波导谐振器,并结合量子电路制冷机(QCR)实现快速谐振器重置。QCR实现非幺正量子操作以模拟核超极化场景。

英文摘要:

Quantum computers have the potential to efficiently simulate the dynamics of nanoscale NMR systems. In this work we demonstrate that a noisy intermediate-scale quantum computer can be used to simulate and predict nanoscale NMR resonances. In order to minimize the required gate fidelities, we propose a superconducting application-specific Co-Design quantum processor that reduces the number of SWAP gates by over 90 % for chips with more than 20 qubits. The processor consists of transmon qubits capacitively coupled via tunable couplers to a central co-planar waveguide resonator with a quantum circuit refrigerator (QCR) for fast resonator reset. The QCR implements the non-unitary quantum operations required to simulate nuclear hyperpolarization scenarios.
