`We demonstrate our proposal with a 70-qubit, depth-70 Clifford circuit doped with 468 T gates. We use a total of 97 physical qubits to encode this computation in spacetime codes, effectively suppressing gate error rates by 10× after syndrome post-selection, and yielding a state with a fidelity lower bound of 0.284 with 95% confidence.`

Updated: I added the aha-chapter that I was missing.
"Quantum computers try all possibilities in parallel" is the popular line — and it's dangerously misleading. A measurement collapses everything to one random answer, so "parallel" on its own is useless.
The actual move: a quantum algorithm is ONE global linear transformation on a 2^n-amplitude vector, designed so wrong answers destructively cancel and the right one amplifies. Classical searches. Quantum shapes.
Walkthrough with a Grover-style bar chart in four snapshots, plus the full pipeline: superconducting oscillator → Josephson junction → Bell state → amplitude amplification → Shor / Grover / simulation.

A #Biological #Qubit is a quantum bit, often a genetically encoded fluorescent protein or other biological molecule, that functions within a living cell.
These biological qubits are primarily being developed as ultrasensitive quantum sensors to measure minute changes in magnetic fields or temperature.

Due atomi di fosforo hanno imparato a parlare a distanza nel silicio. È il primo entanglement quantistico controllato che risolve il grande paradosso: i qubit ora possono essere isolati E anche comunicare.
La scoperta australiana apre la strada a computer quantistici compatibili con i chip esistenti. Mentre tutti inseguono i grandi numeri, loro hanno puntato sull'eleganza.
Il futuro quantistico parla la lingua del silicio.

Che cos'è e a cosa serve un computer quantistico? Qual è lo stato della ricerca in questo campo? L'ho chiesto a Federica Mantegazzini, fisica che con il suo team a Trento ha creato il primo qubit "italiano". L'ho intervistata per il settimanale Azione.

#Cern: #Qubit aus #Antimaterie demonstriert
Fast eine Minute lang konnte das #Antiproton schwingen. Es war der erste Versuch eines #Antimaterie_Quantum_Bits.
Das Baryon-Antibaryon-Symmetrie-Experiment ( #Base ) vermeldet einen Durchbruch bei der Kontrolle und Untersuchung eines Antiprotons, das zu den #Antibaryonen zählt. In einem komplexen System aus drei Fallen konnte es 50 Sekunden lang zwischen zwei Zuständen schwingen.
