Traditional encryption methods have long been vulnerable to quantum computers but two new analyses suggest a capable enough machine may be built much sooner than previously thought

Inside most photonic chips, light races through tiny optical wires. It carries information far faster than electricity can in many conventional systems.

Google published a paper on March 31 that states that Bitcoin's cryptography could be impacted by quantum computing sooner than previously stated.

Google warns that quantum computers could break crypto sooner than expected, heightening the urgency for post-quantum security across blockchain networks.

Roundtable says scaling quantum systems will hinge on manufacturing, calibration, and quantum-classical integration

Researchers at the University of Massachusetts Amherst have built a chip-scale laser stable enough to control a trapped-ion qubit, removing the need for the bulky reference cavities that currently fill entire optical tables in quantum labs.
