Title:
PASSIVE ERROR CORRECTION OF QUANTUM LOGIC ERRORS
Document Type and Number:
WIPO Patent Application WO/2016/020648
Kind Code:
A3
Abstract:
A quantum logic system (100) arranged to perform passive error correction, the quantum logic system (100) comprising: a plurality of qubits (102), the qubits arranged into a plurality of qubit groups (104)and having a first decay rate; control circuitry (300) to passively constrain the overall state of each qubit group (104); and a plurality of auxiliary quantum objects (114), wherein the auxiliary quantum objects (114) are resonantly coupled to the qubit groups (104) such that errors in any of the plurality of qubits (102) are resonantly transferred to the auxiliary quantum objects (114); and wherein the auxiliary quantum objects (114) have a second decay rate, faster than the first decay rate such that qubit errors resonantly transferred to the auxiliary quantum objects (114) are more likely to decay at the auxiliary quantum objects (114) rather than at the qubit (102) from which they are transferred. To be accompanied, when published, by Figure 4.
