Latest Quantum Breakthroughs

A new method learns an unknown quantum operation with the fewest possible uses, settling an old question

An atom simulator running up to 180 qubits finds quantum states that hold off thermalization

Quantinuum reaches beyond-classical circuits without giving up the field's best gate fidelity.

Weakly open quantum systems started in thermal states need extra conserved quantities to show the Mpemba effect

Theory predicts that a local constraint lets a burst of superradiance entangle the emitting atoms

A single atom read out by the cloud next door, after three regimes of light-matter interaction are mapped

A qubit's own jumps pick out the defects that make its environment remember its past states

Second-order out-of-time-order correlators stay sensitive where scrambling usually erases the dynamics.

Integrated photonics generates GKP states, a key ingredient for fault-tolerant light-based quantum computing.

An interferometric parity measurement in InAs-Al nanowires, a building block a topological qubit would need.

Cat qubits suppress bit-flips in hardware so a small repetition code can handle the rest, below threshold.

Oxford teleports a logic gate between trapped-ion modules and runs Grover's search across the link.

Aurora entangles a cluster state across separate chips with 86.4 billion modes, over fiber, at room temperature.

Quantinuum's 56-qubit processor produces over 70,000 bits of entropy verified by exascale classical computing.

A 105-qubit superconducting processor runs a sampling task no classical supercomputer could finish in the age of the universe.
