Hardware Approaches to Qubits
In the race for a quantum computer, one of the major challenges is creating reliable and long-lived qubits. These must be macroscopic in size and yet have quantum properties associated with atoms and subatomic particles, such as quantized energy levels, entanglement, and superposition of states. There are at least a dozen approaches being pursued, and others envisioned but not yet proven. In this session, IBM's Principal Quantum Scientist describes the company's work and recent successes in developing superconducting qubits and, equally important, packaging them. IBM has pledged to unveil, this year, a machine with more than 1,000 qubits, which will set a new mark for a general-purpose quantum computer. Also in this session, physicist Guy Ramon explains the theory and recent progress in spin qubits, and a researcher at UC Davis explains her recent research in using semiconductor defects as the basis of quantum qubits.
