چکیده

As a fundamental concept, geometry is widely used in understanding physical phenomena. In quantum mechanics, related to the system’s state and can be characterized by geometric tensor (QGT), whose real part referred as metric (QMT), which defines distance between two neighboring states projected Hilbert space. Several pieces of research based on discrete variables have been proposed extract QMT, but with use continuous lacking. Here, we propose method QMT variable system, specified here cat-qubit. The developed constructing Kerr nonlinear parametric oscillator (KNPO) modulating it external drives induce adiabatic dynamics process within subspace spanned even odd Scho¨dinger cat states. paves way for exploring systems.

Tensor polarizability measurement by a quantum beat method

2014 Electronic orientation is produced via second order Stark effect by applying an oblique electric field on excited atomic levels previously aligned by beam-foil interaction. Frequencies of alignment and orientation modulations are measured in helium as a function of the applied electric field strength. The deduced tensor polarizabilities of the 4He (n 1D, n = 3, 4, 5) levels are compared wi...

Developing a Method for Increasing Accuracy and Precision in Measurement System Analysis: A Fuzzy Approach

Measurement systems analysis (MSA) has been applied in different aspect of industrial assessments to evaluate various types of quantitative and qualitative measures. Qualification of a measurement system depends on two important features: accuracy and precision. Since the capability of each quality system is severely related to the capability of its measurement system, the weakness of the two...

Efficient measurement-based quantum computing with continuous-variable systems

We present strictly efficient schemes for scalable measurement-based quantum computing using continuousvariable systems: These schemes are based on suitable non-Gaussian resource states, ones that can be prepared using interactions of light with matter systems or even purely optically. Merely Gaussian measurements such as optical homodyning as well as photon counting measurements are required, ...

Continuous measurement of a non-Markovian open quantum system.

Continuous quantum measurement is the backbone of various methods in quantum control, quantum metrology, and quantum information. Here, we present a generalized formulation of dispersive measurement of a complex quantum systems. We describe the complex system as an open quantum system that is strongly coupled to a non-Markovian environment, enabling the treatment of a broad variety of natural o...
