The first quantum computer has been unveiled by IBM with more than 1,000 qubits, which is equivalent to digital bits in a normal computer.
IBM has been following a quantum-computing roadmap for four years, roughly doubling the number of qubits each year.
On 4 December, the chip was unveiled, named Condor.
It has 1,121 superconducting qubits arranged in a honeycomb pattern.
It also launched a 127-qubit chip in 2021 and a 433-qubit chip in 2022.
Quantum computers promise to perform some calculations that are beyond the reach of classical computers.
They will do this by taking advantage of special quantum phenomena such as entanglement and superposition, which allow multiple qubits to exist in multiple collective states simultaneously.
As part of its new effort, the company also unveiled a chip called Heron that has 133 qubits.
But with a record-low error rate, it is three times lower than its previous quantum processor.
