Analog quantum simulation of field theory with a superconducting transmission line
Ilan T. Rosen, Neill C. Warrington, Max Hays +4
Understanding the dynamics of interacting quantum fields remains a fundamental challenge. We propose a superconducting transmission line for analog quantum simulation of -di…
Hardware-efficient erasure-error detection with an integer fluxonium
Junyoung An, Helin Zhang, Jeffrey M. Gertler +13
Erasure-error detection can improve the efficiency of quantum error correction by revealing the times and locations of their error events. In this work, we demonstrate erasure conv…
Observable Estimation in the Absence of Classical Verification
Samantha V. Barron, Bradley Mitchell, Vinay Tripathi +45
The predictive success of quantum mechanics underpins many areas of modern science, even as the exact simulation of large, interacting quantum systems remains beyond the reach of c…
Preparing thermal states of frustrated quantum spin systems using 139 qubits
Roland C. Farrell, Yongtao Zhan, Lucas Katschke +3
Finite-temperature properties of strongly correlated quantum matter are central to condensed matter, chemistry, and high-energy physics, yet are often inaccessible to classical met…
ZZ-Free Two-Transmon CZ Gate Mediated by a Fluxonium Coupler
Junyoung An, Helin Zhang, Qi Ding +19
Eliminating residual ZZ interactions in a two-qubit system is essential for reducing coherent errors during quantum operations. In a superconducting circuit platform, coupling two…
Emergent Harmonics in Josephson Tunnel Junctions Due to Series Inductance
Junghyun Kim, Max Hays, Ilan T. Rosen +11
Josephson tunnel junctions are essential elements of superconducting quantum circuits. The operability of these circuits presumes a -periodic sinusoidal potential of a tunnel j…
Flat-band (de)localization emulated with a superconducting qubit array
Ilan T. Rosen, Sarah Muschinske, Cora N. Barrett +10
Arrays of coupled superconducting qubits are analog quantum simulators able to emulate a wide range of tight-binding models in parameter regimes that are difficult to access or adj…
Qubit-State Purity Oscillations from Anisotropic Transverse Noise
David A. Rower, Kotaro Hida, Lamia Ateshian +13
We explore the dynamics of qubit-state purity in the presence of transverse noise that is anisotropically distributed in the Bloch-sphere XY plane. We perform Ramsey experiments wi…
Remote Entangling Gates for Spin Qubits in Quantum Dots using a Charge-Sensitive Superconducting Coupler
Harry Hanlim Kang, Ilan T. Rosen, Max Hays +2
We propose a method to realize microwave-activated CZ gates between two remote spin qubits in quantum dots using a charge-sensitive superconducting coupler. The qubits are longitud…
Suppressing Counter-Rotating Errors for Fast Single-Qubit Gates with Fluxonium
David A. Rower, Leon Ding, Helin Zhang +12
Qubit decoherence unavoidably degrades the fidelity of quantum logic gates. Accordingly, realizing gates that are as fast as possible is a guiding principle for qubit control, nece…
Attention to Quantum Complexity
Hyejin Kim, Yiqing Zhou, Yichen Xu +10
The imminent era of error-corrected quantum computing urgently demands robust methods to characterize complex quantum states, even from limited and noisy measurements. We introduce…
Implementing a synthetic magnetic vector potential in a 2D superconducting qubit array
Ilan T. Rosen, Sarah Muschinske, Cora N. Barrett +14
Superconducting quantum processors are a compelling platform for analog quantum simulation due to the precision control, fast operation, and site-resolved readout inherent to the h…
