Title: Hole spin qubits
Abstract: Interest in spin-based quantum bits in solids has greatly intensified in the quantum information community in recent years. Besides the small on-chip areas and well-understood qubit manipulation and coupling schemes of spin qubits, recent experiments have shown that spin qubits possess the longest coherence times of all solid-state qubits in isotope purified materials, from seconds to minutes. One of these materials, silicon, is the workhorse of the microelectronic industry. In this seminar I will introduce the concept of spin qubits, how they are fabricated, measured, and how logic gates are performed on them. I discuss recent efforts on hole spin-based quantum bits, which offer certain advantages for scalability, but have traditionally not possessed long coherence times. I will present our results demonstrating record-long hole spin coherence times in silicon, hole spin qubit readout in an industrially fabricated transistor, and prospects for applications of spin qubits in quantum simulators.
