Stabilizer Learning under Global Depolarizing Noise with Polynomial Copies and Time
Aryeh Lev Zabokritskiy
We study learning the stabilizer structure of an unknown pure -qubit state observed through global depolarizing noise of unknown strength, with a fixed promised upper bound belo…
Optimal GHZ extraction from MABK violations
Avraham Kreindel, Aryeh Lev Zabokritskiy
We determine the least Greenberger-Horne-Zeilinger (GHZ) extractability compatible with a Mermin-Ardehali-Belinskii-Klyshko (MABK) Bell score for every . Extractability is…
Quantum Leakage from Shamir Sharing with Correlated Resources
Isaac Barouch Essayag, Aryeh Lev Zabokritskiy
We bound local quantum leakage from Shamir sharing uniformly over prime fields and permitted share-dependent channels. The adversary receives all outputs and a reference to a resou…
Efficient Non-Uniform Quantum Hermite Transform through Adaptive Sampling
Nitay Mayo, Aryeh Lev Zabokritskiy
On the span of the first oscillator modes, Gauss--Hermite quadrature gives an exact change of basis between mode coefficients and weighted position space samples. We implem…
Correcting Connectivity in Arc-Based QUBO Models for Fixed-Fleet Vehicle Routing
Omer Gurevich, Maor Matityahu, Tal Mor +1
We revisit a degree-only arc Hamiltonian for fixed-fleet, homogeneous, uncapacitated vehicle routing. Its local penalties define only a cycle cover, so ground states may contain cu…
From Round-Trip State Echo to Error Recovery: Snapshot-Resolved Quantum-Hardware Diagnostics
Isaac Barouch Essayag, Aryeh Lev Zabokritskiy
We examine which conclusions from quantum-hardware benchmarks persist when the same programs are run again. On eight fixed routes of IQM Emerald, round-trip state echo (RTSE), a di…
How Far Can You Do Nothing On a Quantum Computer?
Nitay Mayo, Tal Mor, Aryeh Lev Zabokritskiy
We present a route-resolved comparative assessment of Rigetti's Cepheus-1-108Q and IBM Heron-r2 processors using the established do-nothing state-transfer protocol. Rather than pro…
