Optimization of Two-Qubit Gates in Tunable-Coupler Architectures Using Single Flux Quantum Control
Boyan Torosov, Bohdan Kulchytskyy, Florian Hopfmueller +3
We present a gradient-based method to construct high-fidelity, two-qubit quantum gates in a system consisting of two transmon qubits coupled via a tunable coupler. In particular, w…
How to Build a Quantum Supercomputer: Scaling from Hundreds to Millions of Qubits
Masoud Mohseni, Artur Scherer, K. Grace Johnson +48
In the span of four decades, quantum computation has evolved from an intellectual curiosity to a potentially realizable technology. Today, small-scale demonstrations have become po…
Optimizing Multi-level Magic State Factories for Fault-Tolerant Quantum Architectures
Allyson Silva, Artur Scherer, Zak Webb +11
We propose a novel technique for optimizing a modular fault-tolerant quantum computing architecture, taking into account any desired space-time trade-offs between the number of phy…
Optimizing Pulse Shapes of an Echoed Conditional Displacement Gate in a Superconducting Bosonic System
Maxime Lapointe-Major, Yongchao Tang, Mehmet Canturk +1
Echoed conditional displacement (ECD) gates for bosonic systems have become the key element for real-time quantum error correction beyond the break-even point. These gates are char…
Multi-qubit Lattice Surgery Scheduling
Allyson Silva, Xiangyi Zhang, Zak Webb +7
Fault-tolerant quantum computation using two-dimensional topological quantum error correcting codes can benefit from multi-qubit long-range operations. By using simple commutation…
Bootstrapping Classical Shadows for Neural Quantum State Tomography
Wirawat Kokaew, Bohdan Kulchytskyy, Shunji Matsuura +1
We investigate the advantages of using autoregressive neural quantum states as ansatze for classical shadow tomography to improve its predictive power. We introduce a novel estimat…
