Continuous-variable designs and design-based shadow tomography from random lattices
Jonathan Conrad, Joseph T. Iosue, Ansgar G. Burchards +1
We investigate state designs for continuous-variable quantum systems using the aid of lattice-like quantum states. These are code states of Gottesman-Kitaev-Preskill (GKP) codes. W…
Correlated Noise Estimation with Quantum Sensor Networks
Anthony J. Brady, Yu-Xin Wang, Victor V. Albert +2
We address the metrological problem of estimating collective stochastic properties imprinted on a network of quantum sensors. Canonical examples include center-of-mass quadrature f…
Numerical evidence for the non-Abelian eigenstate thermalization hypothesis
Aleksander Lasek, Jae Dong Noh, Jade LeSchack +1
The eigenstate thermalization hypothesis (ETH) explains how generic quantum many-body systems thermalize internally. It implies that local operators' time-averaged expectation valu…
Emergent unitary designs for encoded qubits from coherent errors and syndrome measurements
Zihan Cheng, Eric Huang, Vedika Khemani +2
Unitary -designs are distributions of unitary gates that match the Haar distribution up to its -th statistical moment. They are a crucial resource for randomized quantum prot…
Efficient preparation of Dicke states
Jeffery Yu, Sean R. Muleady, Yu-Xin Wang +3
We present an algorithm utilizing mid-circuit measurement and feedback that prepares Dicke states with polylogarithmically many ancillas and polylogarithmic depth. Our algorithm us…
String-Breaking Dynamics in Quantum Adiabatic and Diabatic Processes
Federica Maria Surace, Alessio Lerose, Or Katz +10
Confinement prohibits isolation of color charges, e.g., quarks, in nature via a process called string breaking: the separation of two charges results in an increase in the energy o…
Letting the tiger out of its cage: bosonic coding without concatenation
Yijia Xu, Yixu Wang, Christophe Vuillot +1
Continuous-variable cat codes are encodings into a single photonic or phononic mode that offer a promising avenue for hardware-efficient fault-tolerant quantum computation. Protect…
Geometric structure and transversal logic of quantum Reed-Muller codes
Alexander Barg, Nolan J. Coble, Dominik Hangleiter +1
Designing efficient and noise-tolerant quantum computation protocols generally begins with an understanding of quantum error-correcting codes and their native logical operations. T…
Observing tight triple uncertainty relations in two-qubit systems
Yan Wang, Jie Zhou, Xing-Yan Fan +8
As the fundamental tool in quantum information science, the uncertainty principle is essential for manifesting nonclassical properties of quantum systems. Plenty of efforts on the…
Tessellation codes: encoded quantum gates by geometric rotation
Yixu Wang, Yijia Xu, Zi-Wen Liu
We utilize the symmetry groups of regular tessellations on two-dimensional surfaces of different constant curvatures, including spheres, Euclidean planes and hyperbolic planes, to…
Suppressing chaos with mixed superconducting qubit devices
Ben Blain, Giampiero Marchegiani, Luigi Amico +1
In quantum information processing, a tension between two different tasks occurs: while qubits' states can be preserved by isolating them, quantum gates can be realized only through…
Fast-forwarding quantum algorithms for linear dissipative differential equations
Dong An, Akwum Onwunta, Gengzhi Yang
We establish improved complexity estimates of quantum algorithms for linear dissipative ordinary differential equations (ODEs) and show that the time dependence can be fast-forward…
Instability of steady-state mixed-state symmetry-protected topological order to strong-to-weak spontaneous symmetry breaking
Jeet Shah, Christopher Fechisin, Yu-Xin Wang +6
Recent experimental progress in controlling open quantum systems enables the pursuit of mixed-state nonequilibrium quantum phases. We investigate whether open quantum systems hosti…
Single-shot preparation of hypergraph product codes via dimension jump

Quantum error correction is a fundamental primitive of fault-tolerant quantum computing. But in order for error correction to proceed, one must first prepare the codespace of the u…

We show that a subset of the basis for the irreducible representations of a tensor-product SU(2) rotation forms a covariant approximate quantum error-correcting code with transvers…
Streaming Belief Propagation on Mixed-Alphabet Tanner Graphs for Practical Quantum Memory
Kao-Yueh Kuo, Ching-Yi Lai
Reliable quantum memory under circuit-level noise requires decoders that can process syndrome information continuously and at a rate comparable to its generation. In practical quan…
Dynamically generated concatenated codes and their phase diagrams
Grace M. Sommers, David A. Huse, Michael J. Gullans
We formulate code concatenation as the action of a unitary quantum circuit on an expanding tree geometry and find that for certain classes of gates, applied identically at each nod…
Effective Distance of Higher Dimensional HGPs and Weight-Reduced Quantum LDPC Codes
Shi Jie Samuel Tan, Lev Stambler
Quantum error correction plays a prominent role in the realization of quantum computation, and quantum low-density parity-check (qLDPC) codes are believed to be practically useful…
Resilience-Runtime Tradeoff Relations for Quantum Algorithms
Luis Pedro García-Pintos, Tom O'Leary, Tanmoy Biswas +4
A leading approach to algorithm design aims to minimize the number of operations in an algorithm's compilation. One intuitively expects that reducing the number of operations may d…
Transversal Clifford and T-gate codes of short length and high distance
Shubham P. Jain, Victor V. Albert
The non-local interactions in several quantum device architectures allow for the realization of more compact quantum encodings while retaining the same degree of protection against…
