Google announces at its annual I/O conference:
Within the decade, Google aims to build a useful, error-corrected quantum computer. ...Got that? Google claims that it has achieved quantum supremacy, but it is still a long way from building a system with even one logical qubit.
To begin our journey, today we’re unveiling our new Quantum AI campus in Santa Barbara, California. ...
[wild futuristic hype snipped]
To reach this goal, we’re on a journey to build 1,000,000 physical qubits that work in concert inside a room-sized error-corrected quantum computer. That’s a big leap from today’s modestly-sized systems of fewer than 100 qubits.
To get there, we must build the world’s first “quantum transistor” — two error-corrected “logical qubits” performing quantum operations together — and then figure out how to tile hundreds to thousands of them to form the error-corrected quantum computer. That will take years.
To get there, we need to show we can encode one logical qubit — with 1,000 physical qubits.
