Few measurement shots challenge generalization in learning to classify entanglement
Leonardo Banchi, Jason Pereira, Marco Zamboni
The ability to extract general laws from a few known examples depends on the complexity of the problem and on the amount of training data. In the quantum setting, the learner's gen…
Quantum spatial search with multiple excitations
Dylan Lewis, Leonardo Banchi, Sougato Bose
Spatial search is the problem of finding a marked vertex in a graph. A continuous-time quantum walk in the single-excitation subspace of an spin system solves the problem of sp…
Learning to Classify Quantum Phases of Matter with a Few Measurements
Mehran Khosrojerdi, Jason L. Pereira, Alessandro Cuccoli +1
We study the identification of quantum phases of matter, at zero temperature, when only part of the phase diagram is known in advance. Following a supervised learning approach, we…
Online Convex Optimization of Programmable Quantum Computers to Simulate Time-Varying Quantum Channels
Hari Hara Suthan Chittoor, Osvaldo Simeone, Leonardo Banchi +1
Simulating quantum channels is a fundamental primitive in quantum computing, since quantum channels define general (trace-preserving) quantum operations. An arbitrary quantum chann…
Ion Trap Long-Range XY Model for Quantum State Transfer and Optimal Spatial Search
Dylan Lewis, Leonardo Banchi, Yi Hong Teoh +2
Linear ion trap chains are a promising platform for quantum computation and simulation. The XY model with long-range interactions can be implemented with a single side-band Molmer-…
Reworking the Zubarev's approach to non-equilibrium quantum statistical mechanics
F. Becattini, M. Buzzegoli, E. Grossi
In this work the non-equilibrium density operator approach introduced by Zubarev more than 50 years ago to describe quantum systems at local thermodynamic equilibrium is revisited.…
