Q2020 Systems VisionBen Keitch
Q2020 – Top level System• Nodes need 1x0.6x0.6m volume• Need to be close together (photonic entanglement ~1m) • Either 20x 0.7m high units or 7x full-height racks:
TECHNOLOGY SUBSYSTEMS1. Optical X-Connect2. Optical Power
Supply3. Beam delivery4. Ion trap module5. Control System
Q2020 – Single node : 1, 3, 4 & 5Ion trap, vacuum, RF driver, magnetics, and optics on 2-level bread boardAmps and drivers
DDS and local control
Forced-air cooling
Laser Power bus : 2
Diode lasers (ECDL) boughtTiSaph and pulsed laser boughtStabilisation and control in placeEnough power available for 20 units (?)– Can amplify with injected slaves– Microwaves might reduce requirements
Q2020 – Trap and Optics : 1, 3 & 4
