Quantum entanglement could connect drones for disaster relief, bypassing traditional networks
Any time you use a device to communicate information—an email, a text message, any data transfer—the information in that transmission crosses the open internet, where it could be intercepted. Such communications are also reliant on internet connectivity, often including wireless signal on either or both ends of a transmission.
Scientists build a quantum computer that can repair itself using recycled atoms
Like their conventional counterparts, quantum computers can also break down. They can sometimes lose the atoms they manipulate to function, which can stop calculations dead in their tracks. But scientists at the US-based firm Atom Computing have demonstrated a solution that allows a quantum computer to repair itself while it's still running.
Why quantum computers have memory problems over time
A team of Australian and international scientists has, for the first time, created a full picture of how errors unfold over time inside a quantum computer—a breakthrough that could help make future quantum machines far more reliable.

Record-breaking feat means information lasts 15 times longer in new kind of quantum processor than those used by Google and IBM
The novel design for the new qubit uses the chemical element tantalum in tandem with a special silicon substrate, creating what researchers say are the most coherent superconducting qubits to date.
Breakthrough 3D wiring architecture enables 10,000-qubit quantum processors
The novel 3D wiring architecture and chip fabrication method enable quantum processing units containing 10,000 qubits to fit in a smaller space than today's 100-qubit chips.
New 'physics shortcut' lets laptops tackle quantum problems once reserved for supercomputers and AI
Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours.

Google Quantum AI realizes three dynamic surface code implementations
Quantum computers are computing systems that process information leveraging quantum mechanical effects. These computers rely on qubits (i.e., the quantum equivalent of bits), which can store information in a mixture of states, as opposed to binary states (0 or 1).

New semiconductor could allow classical and quantum computing on the same chip, thanks to superconductivity breakthrough
Researchers believe they can fit 25 million Josephson junctions — a useful component for quantum computing — on one two-inch wafer with this approach.
Quantum computers just simulated physics too complex for supercomputers
Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical computers cannot handle. The achievement demonstrates a new path toward simulating particle collisions and extreme forms of matter. It may ultimately illuminate long-standing cosmic mysteries.
