Quantum Computing

Ultra-deep tech startup Nirvanic put on a fairly humble-looking robotics demo at Jeff Bezos's private MARS 2025 conference – but it may go down as a landmark moment both in AI robotics, and in our understanding of consciousness itself.

Silicon is so important for electronics and computing that it’s become synonymous with technology, but the stuff has its flaws. Now scientists have created a way to make super-pure silicon chips that could pave the way for stable quantum computers.

You can cram much more quantum processing power into a given space if you use four different ways to store data on a single atom, according to new research. The method unlocks more powerful quantum computers that are easier to control.

A DARPA program is claiming a major breakthrough in quantum computing. The Optimization with Noisy Intermediate-Scale Quantum devices (ONISQ) program has created the world's first quantum circuit with logical quantum bits (qubits).

Atom Computing has announced the first quantum computer to pass the 1,000-qubit milestone. The prototype, due to become available for use in 2024, leapfrogs IBM’s announcement of its new quantum computer platform expected in the next few weeks.

A brand new form of silicon might help extend its use into the future. Engineers at North Carolina State University have discovered a material called Q-silicon, with new properties that could have important uses in quantum computers and spintronics.

IBM has unveiled the most powerful quantum processor in the world – the Osprey, with a massive 433 quantum bits (qubits). The new chip headlines a raft of advances in quantum computers announced, as the company prepares for a massive leap next year.

Many quantum effects can only be produced at extremely cold temperatures, which limits how useful they would be in real-world tech. Now, Princeton researchers have demonstrated a strange quantum state taking place in a material at room temperature.

Scientists have demonstrated a technique to allow quantum computers to store more information in photons of light. The team encoded eight levels of data into photons and read it back easily, representing an exponential leap over previous systems.

Quantum computing requires extremely cold temperatures. To that end, IBM has built and demonstrated a huge “super-fridge” codenamed Project Goldeneye that chills things colder than outer space.

Researchers in Germany have demonstrated quantum entanglement of two atoms separated by 33 km (20.5 miles) of fiber optics. This is a record distance for this kind of communication and marks a breakthrough towards a fast and secure quantum internet.

Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound waves.
