Ultraviolet nanosecond pulses added fresh light-emitting flaws in a diamond crystal without disturbing the nitrogen-vacancy centers used in quantum sensors.
Marko Lončar's lab 'dressed' a silicon-vacancy spin with phonons instead of microwave pulses. The technique works inside the phononic cavities that would link nodes of a chip-scale quantum network, letting sound do both jobs at once.
A photon emitted by a qubit is loud at first and fades like a struck bell, which is exactly the wrong shape for the next qubit to absorb. Engineering the waveguide's dispersion reverses the pulse and pushes the absorption probability to 100% in theory.
Using tensor networks to compress the state of hundreds of entangled qubits, researchers cracked a quantum-dynamics calculation on ordinary hardware — matching a quantum computer's results and shaking up claims of 'quantum advantage.'
By cooling ultra-pure crystals to a fraction of a degree above absolute zero, a Vienna-led team stretched the lifetime of magnons to 18 microseconds — long enough to turn them into a 'quantum bus' linking hundreds of qubits.
By cooling ultra-pure crystals to a whisker above absolute zero, a Vienna-led team kept magnons alive for 18 microseconds — long enough, they say, to carry quantum information the way today's best qubits do.
Using a toric code run over dozens of cycles, the company showed its logical error rate fell as it added qubits — a milestone on the long road to fault-tolerant quantum computing.
Researchers at the Flatiron Institute and Boston University adapted a 1980s algorithm to simulate the dynamics of hundreds of qubits on classical computers, undercutting a 2025 claim that the feat required a quantum machine.
A Physical Review B paper shows that periodically switching the magnetic flux in a 2D material produces exotic, topologically protected quantum phases with no static counterpart — a possible path to qubits that are much harder to dephase.
A Chalmers University team merged two quantum physics concepts — giant atoms and superatoms — into a system that uses quantum self-interference to shield qubits from decoherence, the primary barrier to scalable quantum computing.
Breakthrough design from Swedish researchers enables quantum information to be protected and controlled in new ways, potentially bringing large-scale quantum computers closer to reality.
A new error-correction architecture developed with startup Oratomic could accelerate fault-tolerant quantum computing by a decade.
By giving every atom its own miniature mirror resonator to capture escaping photons, Stanford physicists demonstrated a 40-qubit array and a 500-cavity prototype — the clearest route yet to quantum systems far beyond today's best machines.
By operating control electronics at millikelvin temperatures alongside the qubits themselves — a breakthrough that physicists called theoretically infeasible for decades — D-Wave has demonstrated a credible path to quantum computers with hundreds of thousands of qubits.
By operating control electronics at near-absolute-zero temperatures alongside the trapped ions themselves, researchers from Fermilab and MIT Lincoln Laboratory have demonstrated a path to millions of qubits that bypasses the wiring bottleneck that has stalled quantum computing scale-up.
