IBM has unveiled an advanced "quantum" processor that is part of an effort to build super-fast computers, BBC reported.
But the hurdles in building practical, large-scale versions have kept quantum computers confined to the lab, BBC reported.
The new chip has 127 "qubits", twice as many as the previous IBM processor.
Qubits (quantum bits) are the most basic units of information in a quantum computer.
The company called its new Eagle processor "a key milestone on the path towards practical quantum computation".
But one quantum computing expert said more details were needed to assess whether it represented a significant advance.
