The National Science Foundation is seeking a quantum-chip-making process that will work with any one of the quantum-computing architectures being proposed today.
Today, researchers experimenting with quantum computer chips must craft their own process technology. The problem: quantum dots store information in domains that are only a few square nanometers, containing 50 to 10,000 atoms per stored quantum bit (qubit).
Individual devices can be hand-assembled using a scanning… read more
