New advances, how much more valuable?
AN IBM QUANTUM COMPUTER WILL SOON PASS THE 1,000-QUBIT MARK
The Condor processor is just one quantum-computing advance slated for 2023
CHARLES Q. CHOI
IBM’S CONDOR, THE world’s first universal quantum computer with more than 1,000 qubits, is set to debut in 2023. The year is also expected to see IBM launch Heron, the first of a new flock of modular quantum processors that the company says may help it produce quantum computers with more than 4,000 qubits by 2025.
While quantum computers can, in theory, quickly find answers to problems that classical computers would take eons to solve, today’s quantum hardware is still short on qubits, limiting its usefulness. Entanglement and other quantum states necessary for quantum computation are infamously fragile, being susceptible to heat and other disturbances, which makes scaling up the number of qubits a huge technical challenge.
Nevertheless, IBM has steadily increased its qubit numbers. In 2016, it put the first quantum computer in the cloud anyone to experiment with—a device with 5 qubits, each a superconducting circuit cooled to near absolute zero. In 2019, the company created the 27-qubit Falcon; in 2020, the 65-qubit Hummingbird; in 2021, the 127-qubit Eagle, the first quantum processor with more than 100 qubits; and in 2022, the 433-qubit Osprey. ...
