The development of quantum networking requires architectures capable of dynamically reconfigurable entanglement distribution to meet diverse user needs and ensure tolerance against transmission disruptions.
The invention addresses a key challenge in modern computational science: effectively integrating quantum computing capabilities into existing high-performance computing (HPC) environments.
A ZALM source design is described that leverages time-bin entanglement and uses spectral shearing (a.k.a, serrodyne modulation) for spectral shifts.
Accounting for triple excitation effects is essential for achieving high-fidelity quantum chemical simulations. However, current quantum hardware cannot efficiently prepare the highly accurate wavefunctions required to capture these effects directly.
Achieving chemical accuracy—typically defined as errors below 1.6 milliHartree relative to experiment—requires highly accurate wavefunctions, which in turn demand deep and wide quantum circuits.
We describe a novel approach for detecting and spatially mapping boron vacancy spin defects in hexagonal boron nitride using a scanning nitrogen-vacancy (NV) center microscope.
This invention discloses a system, method, and device for real-time monitoring, verification, and security enforcement in quantum and hybrid quantum-classical systems.
Cluster states are key to measurement-based quantum computing. In particular, continuous variable cluster states provide several advantages over typical discrete variables approaches, including deterministic generation and room-temperature operation.
Our work shows how to derive a set of consistent interactions between a parent topological phase (Z_4) and a condensed variant thereof (DS). We then show how N condensed DS patches embedded within a Z_4 matrix realize N-1 logical error corrected qubits.
