Polynomial-time additive-error estimation of output probabilities for shallow quantum circuits
We give a deterministic classical algorithm that estimates $|\langle x|U|0^n\rangle|^2$ to additive error $\varepsilon$ in $\mathrm{poly}(n, 1/\varepsilon)$ time, where $U$ is a constant-depth…The Robustness of QAC0
In this work we study the robustness of $\mathsf{QAC}^0$ with respect to error tolerance and modifications to its gate-set.Learning Many-Body Hamiltonians Using a Local Probe
Hamiltonian learning provides a systematic framework for reconstructing unknown quantum dynamics.Beyond Light Cones: State Preparation Complexity in Quantum Spin Glasses
We introduce a method for studying state preparation complexity in dense quantum $p$-spin Hamiltonians on $n$ qubits, going beyond bounds based only on circuit lightcones.Polynomial-time classical and quantum simulation of quantum impurity models
Quantum impurity models are paradigmatic models of interacting quantum matter, as well as key computational primitives for modern electronic-structure methods.Robust exponential lower bounds for fermionic and bosonic Gaussian ranks
The power and limitations of classical simulation are central to understanding quantum computational advantages.From Permutation Symmetry to Communication Bounds and Additivity
Correlations across channel uses can improve quantum communication rates, making optimization over arbitrarily large blocks a central difficulty in determining quantum capacity.Learning SYK Hamiltonians
We study the problem of learning the dense Sachdev--Ye--Kitaev (SYK) Hamiltonian from copies of its Gibbs state.Single-Particle Spectral Estimation
We study Hamiltonian learning in a novel setting, where we are promised a physical structure that is obfuscated by a global unitary.Premonoidal Semantics and Scalable Diagrammatics of Fermionic Quantum Computing
Local fermionic mode (LFM) based quantum computation has pure state spaces that are isomorphic, via the Jordan-Wigner representation, to qubit state spaces, but its compositional structure is subtly…A Semiclassical Entanglement Wedge in Double-Scaled SYK
We study the entanglement structure of partially entangled thermal states in double-scaled SYK , allowing flavor degrees of freedom carried by matter insertions to be in an arbitrary mixed state.Entanglement Requires Fluctuations at Conformal Interfaces
We conjecture that the universal logarithmic coefficient for capacity of entanglement $c_{\mathrm{cap}}$ is bounded below by the corresponding entropy coefficient $c_{\mathrm{eff}}$ at conformal…Homological Thresholds in Randomly Monitored Quantum Error-Correcting Codes
Random projective measurements are an effective tool to model the interlinked phenomenology of monitoring, inferring, and decoding highly entangled states such as quantum error-correcting codes.Counterdiabatic Quantum Circuits
Counterdiabatic driving provides a universal route to fast quantum control, but its standard formulation presupposes a Hamiltonian generator.How Quantum Is Bottomonium in the Quark-Gluon Plasma?
We study how much quantum structure bottomonium retains during its evolution in the quark-gluon plasma.Gap-Protected Heisenberg-Limited Squeezing with Locally Interacting Multi-Level Spins
We demonstrate a general mechanism to generate scalable, metrologically useful entanglement in the form of generalized spin squeezing in multi-level (qudit) spin systems with power-law interactions.Halving the cost of QROM again via dense encoding
Quantum read only memory (QROM) is a substantial source of non-Clifford cost in fault-tolerant quantum algorithms.From Static Lindblad Stabilizability to Robust Physical Control Sequences
Dissipative dynamics can stabilize a quantum target without providing a reliable sequence of finite control operations.Singer-Difference-Set Qudit Stabilizer Codes from Non-Degenerate Quadrics in PG(d,q)PG(d,q): Construction, Structural Theorems, and Monte-Carlo Performance
We propose Q(q,d), a family of q-ary non-CSS qudit stabilizer codes with prime power q and dimension d >= 2, constructed from Singer difference sets and non-degenerate quadrics in PG(d,q).Chiral Vacuum Engineering of Quantum Hall Matter
We reveal that a chiral cavity distinguishes the resonant and antiresonant interactions between a two-dimensional electron gas and the cavity vacuum.
