摘要： Computing bus devices that enable quantum information to be coherently transferred between conventional qubit pairs are disclosed. A concrete realization of such a quantum bus acting between conventional semiconductor double quantum dot qubits is described. The disclosed device measures the joint (fermion) parity of the two qubits by using the Aharonov-Casher effect in conjunction with an ancillary superconducting flux qubit that facilitates the measurement. Such a parity measurement, together with the ability to apply Hadamard gates to the two qubits, allows for the production of states in which the qubits are maximally entangled, and for teleporting quantum states between the quantum systems.

摘要： A fusion outcome quasiparticle may be trapped in a potential well of a topological segment. The fusion outcome quasiparticle may be the product of fusion of a first quasiparticle and a second quasiparticle, where the first and the second quasiparticles are localized at ends of a topological segment. The potential well having the fusion outcome quasiparticle trapped therein and a third quasiparticle may be moved relative to each other such that the potential well and the third quasiparticle are brought toward each other. The quasiparticles may be Majorana modes of a nanowire.

摘要： A topological qubit wire hosts Majorana zero-energy modes and includes a superconductor, which may be an s-wave superconductor, and a quasi-1D nanowire, which may be a semi-conductor. The Majorana zero-energy modes are localized at ends of the quasi-1D nanowire, which may be sized and shaped to provide occupancy of a few transverse modes in a first direction and occupancy of a few transverse modes in a second direction. In some instances, the occupancy in the first direction may be greater than or equal to 3, and the occupancy in the second direction may be 1.

摘要： Computing bus devices that enable quantum information to be coherently transferred between topological and conventional qubits are disclosed. A concrete realization of such a topological quantum bus acting between a topological qubit in a Majorana wire network and a conventional semiconductor double quantum dot qubit is described. The disclosed device measures the joint (fermion) parity of the two different qubits by using the Aharonov-Casher effect in conjunction with an ancillary superconducting flux qubit that facilitates the measurement. Such a parity measurement, together with the ability to apply Hadamard gates to the two qubits, allows for the production of states in which the topological and conventional qubits are maximally entangled, and for teleporting quantum states between the topological and conventional quantum systems.
