The problem is to find a stabilizing measurement-free quantum controller for a quantum plant so as to minimize a mean square cost for the fully quantum closed-loop system.
The main idea of our approach is to introduce an additional uncertainty to form an artificial uncertain quantum system used to design the desired quantum controller.
And while quantum computing may someday break today's encryption keys, something called quantum cryptography promises an approach to encryption that cannot be foiled by a quantum computer.
The symmetry of the problem is taken into account by introducing equivalence classes of coherent quantum controllers generated by symplectic similarity transformations.
There is no real reality, except as detected by a Quanta — an individual spirit.
The temperature of the stage was controlled by a TMS94 controller using an S-type thermocouple.
Based on a recently developed notion of physical realizability for quantum linear stochastic systems, we formulate a quantum LQG optimal control problem for quantum linear stochastic systems where the controller itself may also be a quantum system and the plant output signal can be fully quantum.
The color was set by a controller box and remote control.
The XYZ stage controller can also be operated by a remote controller (h).
Battery charge control is performed by a conventional charge controller, which uses a PIC18f876 micro-controller.
