We present a toolbox to probe quantum many-body states implemented on Rydberg-atoms quantum hardware via randomized measurements. We illustrate the efficacy of this measurement toolbox in the context of probing entanglement, via the estimation of the purity, and of verifying a ground-state preparation using measurements of the Hamiltonian variance. To achieve this goal, we develop and discuss in detail a protocol to realize independent, local unitary rotations. We benchmark the protocol by…

Programmable quantum simulators and quantum computers are opening unprecedented opportunities for exploring and exploiting the properties of highly entangled complex quantum systems. The complexity…

Classical Shadows with Noise

This paper considers the scenario in which the quantum circuits involved in the protocol are subject to various known noise channels and derive an analytical upper bound for the sample complexity in terms of a shadow seminorm for both local and global noise.

Is quantum computing green? An estimate for an energy-efficiency quantum advantage

It is shown that the green quantum advantage threshold crucially depends on (a) the quality of the experimental quantum gates and (b) the entanglement generated in the QPU, and algorithms with a power-law decay of singular values of bipartitions are identified as the green Quantum Advantage threshold in the near future.

Entanglement phase diagrams from partial transpose moments

We present experimentally and numerically accessible quantities that can be used to differentiate among various families of random entangled states. To this end, we analyze the entanglement properties…

Scalable and Flexible Classical Shadow Tomography with Tensor Networks

This work demonstrates a scalable classical shadow tomography approach for generic randomized measurements implemented with finite-depth local Clifford random unitary circuits, which interpolates between the limits of Pauli and Cli⬁ord measurements.

Quantum Fisher Information from Randomized Measurements.

This work uses polynomials of the density matrix to construct monotonically increasing lower bounds that converge to the QFI, and proposes a protocol to accurately estimate these lower bounds in state-of-the-art quantum technological platforms.

Efficient estimation of Pauli observables by derandomization

An efficient derandomization procedure is proposed that iteratively replaces random single-qubit measurements by fixed Pauli measurements; the resulting deterministic measurement procedure is guaranteed to perform at least as well as the randomized one.

Symmetry-resolved dynamical purification in synthetic quantum matter

When a quantum system initialized in a product state is subjected to either coherent or incoherent dynamics, the entropy of any of its connected partitions generically increases as a function of…
