A compact sensor for detection of chemical and/or biological compounds in low concentration. The sensor comprises electromagnetic microcavities. The agent to be detected passes the microcavities, is absorbed and/or absorbed by the microcavities, and modifies the electromagnetic field inside the microcavities. After the agent has been adsorbed and/or absorbed, a probe beam is applied to the microcavities. The change of electromagnetic field is detected by the detector, and the frequency of the probe beam at which the resonance is observed, is indicative of a particular agent being present. A method for detecting chemical and/or biological compounds using the sensor.

The present invention is directed to systems and methods of providing universal quantum computation that avoid certain external control fields that either are hard or impossible to implement, or are serious sources of decoherence (errors). The systems and methods extend the set of scalable physical platforms suitable for implementing quantum computation in solid state, condensed matter and atomic and molecular physics systems. The invention includes identifying of suitable encodings of logical qubits into three physical qubits—i.e. three quantum mechanical systems of two levels—and performing quantum computing operations by changing the quantum states of physical qubits making up one or more logical qubits using only generalized anisotropic exchange interactions. This includes performing a quantum unitary operation over a single logical qubit or a non-local (entangling) two-qubit unitary operation. An exemplary embodiment of the invention uses a physical qubit represented by two electronic quantum levels of a nanoparticle supported in an electromagnetic cavity. The physical qubit, i.e. its quantum levels can be tuned by electromagnetic field from a pulsed laser, so that the qubit can be brought into the interaction (resonance) with another physical qubit via exchange of cavity quantum electromagnetic modes.

A system and a method for measuring properties and health of structures are disclosed. The system comprises a number of sensors connected to a single antenna. Each sensor has a body that defines an electromagnetic resonator. The electromagnetic resonator produces a response signal in response to an interrogation signal. The body is coupled to the structure to so as to allow the parameters of interest alter the resonance properties of the electromagnetic resonators thereby altering the response signal. The sensor further includes a coupler that is coupled to the body. The coupler transfers the interrogation signal into the electromagnetic resonator and transfers the response signal from the electromagnetic resonator. The system further includes an interrogator that generates and transmits the interrogation signal to the sensor. The interrogator also receives the response signal.
