Quantum science with arrays of metastable helium-3 atoms

Zheyuan Li, Rupsa De, Rishi Sivakumar +7

The motion of atoms in programmable optical tweezer arrays offers many new opportunities for neutral atom quantum science. These include inter- and intra-site atom motion for resou…

A Spectral Quantum Algorithm for Numerical Differentiation and Integration

Jordan Cioni, Fabio Semperlotti

Numerical calculus algorithms which estimate derivatives and integrals from data series acquired either via measurements or by sampling functions are essential in scientific comput…

Krylov complexity and fidelity susceptibility in two-band Hamiltonians

Rishav Chaudhuri, Ayush Raj, Soham Ray +1

We investigate Krylov spread complexity for the ground state of two-band Hamiltonians, where the reference state is a generic state on the Bloch sphere. The spread complexity is ob…

Entangling Superconducting Qubits via Energy-Selective Local Reservoirs

Qihao Guo, Botao Du, Ruichao Ma

Engineered dissipation provides a powerful route to controlling and stabilizing quantum states in open systems. Superconducting circuits are particularly suited to this approach du…

Topological entanglement entropy meets holographic entropy inequalities

Joydeep Naskar, Sai Satyam Samal

Topological entanglement entropy (TEE) is an efficient way to detect topological order in the ground state of gapped Hamiltonians. The seminal work of Kitaev and Preskill~\cite{pre…

Degrees, Levels, and Profiles of Contextuality

Ehtibar N. Dzhafarov, Victor H. Cervantes

We introduce a new notion, that of a contextuality profile of a system of random variables. Rather than characterizing a system's contextuality by a single number, its overall degr…
