- Berkeley CA, US
Shane Arthur CALDWELL - Oakland CA, US
Michael James CURTIS - Sacramento CA, US
Matthew J. REAGOR - Corte Madera CA, US
Chad Tyler RIGETTI - Walnut Creek CA, US

Assignee:

Rigetti & Co, Inc. - Berkeley CA

International Classification:

G06N 10/00
H03K 19/195

Abstract:

In a general aspect, calibration is performed in a quantum computing system. In some cases, domains of a quantum computing system are identified, where the domains include respective domain control subsystems and respective subsets of quantum circuit devices in a quantum processor of the quantum computing system. Sets of measurements are obtained from one of the domains and stored in memory. Device characteristics of the quantum circuit devices of the domain are obtained based on the set of measurements, and the device characteristics are stored in a memory of the control system. Quantum logic control parameters for the subset of quantum circuit devices of the domain are obtained based on the set of measurements and stored in memory.

Appl. No.:

15/970827

Inventors:

- Enfield, GB
Alex POLLITT - San Francisco CA, US
Michael CURTIS - Sacramento CA, US
Shaun CRAMPTON - San Francisco CA, US

International Classification:

H04L 12/64
H04L 12/851
H04L 12/721
H04L 12/24

Abstract:

A controller node receives a list of a first plurality of flows programmed on a network switch. The controller node extracts a flow cookie value from a flow cookie data field of each flow in the first plurality of flows on the received list and calculates a session identifier on the basis of the extracted cookie values. At least one add flow command is transmitted from the controller node to the network switch to program a second plurality of flows on the network switch. The at least one add flow command comprises flow cookie values in the flow cookie data fields of each of the flows in the second plurality of flows which are set equal to the calculated session identifier. At least one delete flow command is transmitted from the controller node to the network switch to delete programming of the first plurality of flows on the network switch.
