   • 2006 March 25, NewScientist, page 42/2:

     Quantum computing, on the other hand, is based on quantum bits, or qubits.

   • 2012 February 25, ‘An uncertain future’, The Economist:

     Each extra qubit in a quantum machine doubles the number of simultaneous operations it can perform.

   • 2019 October 21, Dennis Overbye, “Quantum Computing Is Coming, Bit by Qubit”, in New York Times‎:

     Google’s Sycamore computer has all of 53 qubits to its name, as does a new IBM computer, installed online at the company’s Quantum Computation Center in Poughkeepsie, N.Y. System One, IBM’s black cube from tomorrow, only has 20 qubits.

   • 2019 October 23, Cade Metz, “Google Claims a Quantum Breakthrough That Could Change Computing”, in New York Times‎:

     By harnessing that odd behavior, scientists can instead build a quantum bit, or qubit, which stores a combination of 1 and 0. Two qubits can hold four values at once. And as the number of qubits grows, a quantum computer becomes exponentially more powerful.
