When are bosonic Gaussian states classical to learn?
Senrui Chen, Antonio Anna Mele, Francesco Anna Mele +1
A fundamental question in physics is: When does classical behavior emerge from quantum systems? Bosonic Gaussian states provide a natural setting to explore this quantum-classical…
Universal equilibrium magic in quantum many-body systems
Soumyadeep Sarma, Tobias Haug, John Preskill +1
Thermalization conventionally describes local properties of isolated many-body systems at equilibrium. Magic, or nonstabilizerness $\unicode{x2013}$ the resource enabling universal…
Near-optimal quantum metrology with few-qubit measurements
Liang Mao, Senrui Chen, Hsin-Yuan Huang +2
Quantum metrology, which addresses parameter estimation in quantum systems, has broad applications across science and technology. Conventional metrology protocols for multi-qubit s…
High-rate qLDPC processors
Aditya Bhardwaj, Muzhou Ma, Nadine Meister +6
Despite significant progress on quantum low-density parity-check (qLDPC) codes, building qLDPC processors that are high-rate, high-throughput, hardware-friendly, and fast-to-decode…
State preparation and detection for quantum simulation of particle collisions
Federica Maria Surace, Sary Bseiso, John Preskill
Simulating the real-time dynamics of particle collisions is a promising application of quantum simulators, because classical methods such as tensor networks struggle to capture the…
Observation of gravity-like signatures in holographic codes on a quantum computer
Debopriyo Biswas, Gong Cheng, Krishnanand Karthikeyan +12
The unification of quantum mechanics and general relativity remains one of the major open problems of theoretical physics. The Anti-de Sitter/Conformal Field Theory (AdS/CFT) corre…
Exponential quantum advantage in processing massive classical data
Haimeng Zhao, Alexander Zlokapa, Hartmut Neven +4
Broadly applicable quantum advantage, particularly in classical data processing and machine learning, has been a fundamental open problem. In this work, we prove that a small quant…
Shor's algorithm is possible with as few as 10,000 reconfigurable atomic qubits
Madelyn Cain, Qian Xu, Robbie King +6
Quantum computers have the potential to perform computational tasks beyond the reach of classical machines. A prominent example is Shor's algorithm for integer factorization and di…
What resources are needed for optimal learning of bosonic Gaussian states?
Senrui Chen, Francesco Anna Mele, Marco Fanizza +5
Continuous-variable systems enable key quantum technologies in computation, communication, and sensing. Bosonic Gaussian states emerge naturally in various such applications, inclu…
State-dependent geometries from magic-enriched quantum codes
ChunJun Cao, Gong Cheng, Krishnanand Karthikeyan +2
Quantum error-correcting codes provide a powerful framework for emergent spacetime, yet existing subsystem erasure-correcting holographic code models describe only quantum fields o…
Chiral Lattice Gauge Theories from Symmetry Disentanglers
Ryan Thorngren, John Preskill, Lukasz Fidkowski
We propose a Hamiltonian framework for constructing chiral gauge theories on the lattice based on symmetry disentanglers: constant-depth circuits of local unitaries that transform…
Nature is stingy: Universality of Scrooge ensembles in quantum many-body systems
Wai-Keong Mok, Tobias Haug, Wen Wei Ho +1
Recent advances in quantum simulators allow direct experimental access to ensembles of pure states generated by measuring part of an isolated quantum many-body system. These projec…
