Spin-Cavity Computing

J. Stajic

Physics Today's (very rudimentary) quantum computers come in different guises, each with their own set of pros and cons. A growing trend has been to put two different technologies together in hybrid architectures in order to have the best of both worlds. One of the aims of such initiatives is to realize long-distance coupling between spin qubits (quantum bits based on electron spins) in quantum dots (zero-dimensional semiconductor nanostructures that allow controlled coupling of one or more electrons) via interactions with a superconducting microwave cavity. Petersson et al. made progress toward that goal by coupling a double quantum dot in an InSb nanowire to the electric field of a cavity, taking advantage of the strong spin-orbit interaction of InSb. The coupling was demonstrated by using a pulse sequence to electrically control the spin state, which was then read out in the phase response of the cavity. The estimated spin-cavity coupling is still shy of the strong limit required for two distant spin qubits to communicate; however, it is expected that improving the quality of the cavity and the coherence of the qubit, and/or using a material with stronger spin-orbit interactions, will bring physicists closer to that goal. Nature 490 , 380 (2012).

Spin and charge localisation due to the interplay of Ac gate voltage and spin–orbit interaction

Kulsoom Rahim, Usman Hasan

We investigate the effects of a time-dependent gate voltage on a spin–orbit interaction (SOI) coupled interacting double quantum dot (DQD) system. For a tunnel coupled detuned DQD with two interacting electrons, SOI couples triplet T0 and hybridised singlet state (1,1)–(0,2) through spin nonconserving transition. In order to explore the effects of Ac gate voltage on charge localisation, we initiate the system in the vicinity of the singlet–triplet avoided crossing and investigate the interplay of the Ac gate voltage and SOI on the charge and spin dynamics of the system. We show that the triplet state (1,1) charge configuration can be frozen by tuning the Ac frequency leading to charge localisation and dynamical spin locking with a redefined spin–orbit field in terms of gate voltage.
