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
The paper proposes practical protocols for preparing incoming wave‑packet states and detecting outgoing scattering products in analog and digital quantum simulators, using an auxil…
Observation of gravity-like signatures in holographic codes on a quantum computer
Debopriyo Biswas, Gong Cheng, Krishnanand Karthikeyan +12
The authors implement a holographic quantum error‑correcting code (the HaPPY code) on a trapped‑ion quantum computer and experimentally verify holographic entropy relations, includ…
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 holographic code models describe only quantum fields on a fixed background: in subs…
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…
