Qubit

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.

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.

Dark matter makes up the majority of matter in the universe, but it’s strangely shy about making its presence known. Now physicists have designed a new test to search for signs of two candidate particles, using the quirky world of quantum technology.

Current-gen quantum computing "qubits" need to be kept incredibly cold – below 0.1 Kelvin (-273.05 °C/-459.5 °F). But new "hot qubits" developed at UNSW can work 15 times hotter, opening the door to radically smaller, cheaper quantum computers.

Scientists from Austria and China throw Schrodinger's Cat for a loop.

Practical quantum computers may be another step closer to reality, thanks again to graphene. The bits of information in quantum computers (qubits) can exist in two states at once, and now researchers have managed to record just how long that superposition state can last in a qubit made of graphene.

With the quantum computing race heating up, it feels like we’re hurtling towards quantum supremacy, when a quantum computer outperforms a classical one for the first time. Google has now unveiled Bristlecone, a new quantum computer chip with the record-setting power of 72 quantum bits (qubits).

The next big breakthrough for electronics is likely to be quantum computers, but there are still plenty of hurdles to jump before they become a reality. A team from Aalto University in Finland may have cleared one of those obstacles, developing a “nanorefrigerator” to help cool components down.

Researchers have recently blasted through another quantum quandary, potentially bringing stability to the notoriously unstable world that exists in these computing systems. New Atlas spoke with one of the researchers to get more information about the potentially game-changing work.
