Free fermions behind the disguise
Samuel J. Elman, Adrian Chapman, Steven T. Flammia
An invaluable method for probing the physics of a quantum many-body spin system is a mapping to noninteracting effective fermions. We find such mappings using only the frustration…
Building a fault-tolerant quantum computer using concatenated cat codes
Christopher Chamberland, Kyungjoo Noh, Patricio Arrangoiz-Arriola +13
We present a comprehensive architectural analysis for a proposed fault-tolerant quantum computer based on cat codes concatenated with outer quantum error-correcting codes. For the…
Robust shadow estimation
Senrui Chen, Wenjun Yu, Pei Zeng +1
Efficiently estimating properties of large and strongly coupled quantum systems is a central focus in many-body physics and quantum information theory. While quantum computers prom…
Quantum coding with low-depth random circuits
Michael J. Gullans, Stefan Krastanov, David A. Huse +2
Random quantum circuits have played a central role in establishing the computational advantages of near-term quantum computers over their conventional counterparts. Here, we use en…
Unboxing Quantum Black Box Models: Learning Non-Markovian Dynamics
Stefan Krastanov, Kade Head-Marsden, Sisi Zhou +3
Characterizing the memory properties of the environment has become critical for the high-fidelity control of qubits and other advanced quantum systems. However, current non-Markovi…
The XZZX Surface Code
J. Pablo Bonilla Ataides, David K. Tuckett, Stephen D. Bartlett +2
Performing large calculations with a quantum computer will likely require a fault-tolerant architecture based on quantum error-correcting codes. The challenge is to design practica…
