Pilot wave theory, developed by Louis de Broglie a century ago, potentially resolves quantum mechanics' paradoxes by describing particles guided by attendant waves rather than existing in superposition.

Ramana Kompella explained that traditional routing methods such as TCP/IP are not suitable for quantum networks because they rely on classical physics. Quantum networks utilize entanglement, where endpoints are connected using entangled photon pairs, allowing for instantaneous information transfer once entanglement is established.

NIST has developed a chip that reliably emits a single photon on demand. This ability will improve the efficiency of QKD (quantum key distribution) as we prepare for the arrival of quantum computers. Quantum computers will upend current cryptology by using Shor's algorithm to rapidly negate the current public/private key secure encryption methods. This has largely been solved by NIST's post quantum cryptology (PQC) algorithms.

Qunnect and Cisco have unveiled what they say is the first entanglement-swapping demonstration of its kind over deployed metro-scale fibre using a commercial quantum networking system. The demonstration combined Qunnect's room-temperature quantum hardware with Cisco's quantum networking software stack. The net result of the project is regarded by the partners as being able to bring practical quantum networks closer to scalable deployment, validating a spoke-and-hub model for scaling quantum networks through commercial datacentres.

Analogue quantum simulations are a useful tool for investigating these systems, particularly in regimes in which the applicability of numerical techniques is limited. For different simulator platforms, figures of merit include the electron bandwidth and interaction strength, temperature and the number of simulated lattice sites. Their use is further underscored by the ability to realize distinct lattice geometries, on-site degrees of freedom and by the physical observables that are accessible to experimental measurement.

1 month agoAsk Ethan: Can quantum entanglement survive a black hole?
According to Einstein's General Relativity, for every black hole that exists within the Universe, there are only three properties that go into it that matter in any way: the black hole's total mass, the black hole's net electric charge, and the black hole's intrinsic angular momentum, and that's it. It doesn't matter what type of matter went into the black hole in order to form it; all that matters is its mass, charge, and angular momentum.
