Quantum computer startup first to break 1,000-qubit milestone leaving IBM in the dust

Good news! Could this be a critical breakthrough?

"... Now, Atom Computing has announced the most advanced quantum computing platform to date, boasting an impressive 1,180 qubits. That’s a huge leap over the previous most powerful quantum computer – IBM’s Osprey, with 433 qubits. ...
Atom claims that its quantum computer excels in other measures too. Earlier this year the company demonstrated mid-circuit measurement – where the quantum state of desired qubits can be probed without disturbing neighboring qubits. The computer also apparently boasts coherence times – a measure of how long qubits can store information – of 40 seconds. By comparison, the Osprey tops out at around 80 microseconds. ..."

"Fault-tolerant quantum computers that can overcome errors during computations and deliver accurate results will require hundreds of thousands, if not millions, of physical qubits along with other key capabilities, including:
  1. Long coherence times. The company has achieved record coherence times by demonstrating its qubits can store quantum information for 40 seconds.
  2. Mid-circuit measurement. Atom demonstrated the ability to measure the quantum state of specific qubits during computation and detect certain types of errors without disturbing other qubits.
  3. High fidelities. Being able to control qubits consistently and accurately to reduce the number of errors that occur during a computation.
  4. Error correction. The ability to correct errors in real time.
  5. Logical qubits. Implementing algorithms and controls to combine large numbers of physical qubits into a “logical qubit” designed to yield correct results even when errors occur. ..."
