论文摘要
量子计算机有可能有效地模拟纳米级NMR系统的动力学。在这项工作中，我们证明了一台嘈杂的中间量子计算机可用于模拟和预测纳米级NMR共振。为了最大程度地减少所需的门的保真度，我们提出了一个超导应用特定的共同设计量子处理器，该处理器将超过20个QUBIT的芯片减少了超过90％的交换门的数量。该处理器由通过可调耦合器的电容耦合到中央共同平面波导谐振器，并带有量子电路冰箱（QCR），用于快速谐振器重置。 QCR实现了模拟核超极化场景所需的非单身量子操作。
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.
