Mesoscopic quadratic quantum measurements.
We develop a theory of quadratic quantum measurements by a mesoscopic detector. It is shown that the quadratic measurements should have nontrivial quantum information properties, providing, for instance, a simple way of entangling two noninteracting qubits. We also calculate the output spectrum of a detector with both linear and quadratic response, continuously monitoring two qubits.
متن کاملA Mesoscopic Quantum Eraser
– Motivated by a recent experiment by Buks et al. [Nature 391, 871 (1998)] we consider electron transport through an Aharonov–Bohm interferometer with a quantum dot in one of its arms. The quantum dot is coupled to a quantum system with a finite number of states acting as a which–path detector. The Aharonov–Bohm interference is calculated using a two–particle scattering approach for the joint t...
متن کاملMesoscopic magnetism and quantum chaos
All seven physics STAIRSTEP students and 15 undergraduate students have participated to a talk about the orbital magnetic susceptibility of electrons in a rectangular box. Mesoscopic systems, such as small metal particles and quantum dots, exhibit many novel properties due to the coherent effect and finite-size quantization. In the mesoscopic regime, magnetic properties are sensitive to whether...
متن کاملA Mesoscopic Quantum Gravity Effect
We explore the symmetry reduced form of a non-perturbative solution to the constraints of quantum gravity corresponding to quantum de Sitter space. The system has a remarkably precise analogy with the non-relativistic formulation of a particle falling in a constant gravitational field that we exploit in our anaylsis. We find that the solution reduces to de Sitter space in the semiclassical limi...
متن کامل3 Negative result measurements in mesoscopic systems
We investigate measurement of electron transport in quantum dot systems by using single-electron transistor as a noninvasive detector. It is demonstrated that such a detector can operate in the " negative-result measurement " regime. In this case the measured current is not distorted, providing that it is a non-coherent one. For a coherent transport, however, the possibility of observing a part...
