Quantum data compression of a qubit ensemble.
Data compression is a ubiquitous aspect of modern information technology, and the advent of quantum information raises the question of what types of compression are feasible for quantum data, where it is especially relevant given the extreme difficulty involved in creating reliable quantum memories. We present a protocol in which an ensemble of quantum bits (qubits) can in principle be perfectl...
متن کاملQuantum Data Compression
Quantum Information Theory is about studying information encoded in quantum systems and exploring their unique properties. The topic of our report is Quantum Data Compression, a central problem to storage and transmission of data. Our report presents an overview of Classical Coding Theory and the main concepts of Quantum Coding Theory. Moreover, we introduce a particular quantum noiseless and l...
متن کاملHybrid quantum circuit with a superconducting qubit coupled to a spin ensemble.
We report the experimental realization of a hybrid quantum circuit combining a superconducting qubit and an ensemble of electronic spins. The qubit, of the transmon type, is coherently coupled to the spin ensemble consisting of nitrogen-vacancy centers in a diamond crystal via a frequency-tunable superconducting resonator acting as a quantum bus. Using this circuit, we prepare a superposition o...
متن کاملBistability in the Electric Current through a Quantum-Dot Capacitively Coupled to a Charge-Qubit
We investigate the electronic transport through a single-level quantum-dot which is capacitively coupled to a charge-qubit. By employing the method of nonequilibrium Green's functions, we calculate the electric current through quantum dot at finite bias voltages. The Green's functions and self-energies of the system are calculated perturbatively and self-consistently to the second order of inte...
متن کاملSchumacher's quantum data compression as a quantum computation.
An explicit algorithm for performing Schumacher’s noiseless compression of quantum bits is given. This algorithm is based on a combinatorial expression for a particular bijection among binary strings. The algorithm, which adheres to the rules of reversible programming, is expressed in a high-level pseudocode language. It is implemented using O(n3) twoand three-bit primitive reversible operation...
