Fisher zeros and persistent temporal oscillations in nonunitary quantum circuits

چکیده
We present a quantum circuit with measurements and postselection that exhibits panoply of space- and/or time-ordered phases from ferromagnetic order to spin-density waves time crystals. Unlike the crystals have been found in unitary models, those occur here are incommensurate drive frequency. The period time-crystal phase may be tuned by adjusting parameters. demonstrate our circuit, including inherently nonequilibrium dynamical ones, correspond complex-temperature equilibrium exactly solvable square-lattice anisotropic Ising model.

Nonunitary quantum circuit
A quantum circuit is generalized to a nonunitary one whose constituents are nonunitary gates operated by quantum measurement. It is shown that a specific type of one-qubit nonunitary gates, the controlled-not gate, as well as all one-qubit unitary gates constitute a universal set of gates for the nonunitary quantum circuit, without the necessity of introducing ancilla qubits. A reversing measur...
متن کاملNonunitary Quantum Theory with a Field Cutoff
We consider a scalar quantum field theory, in which the interaction takes the form of a field cutoff; the energy diverges to infinity whenever the value of the field at some point falls outside a finite interval. In a simple (1+1)-dimensional version of this theory, we may calculate the results of certain scattering processes exactly. The main feature of the nontrivial solutions is the appearan...
متن کاملVolume dependence of Fisher ’ s zeros
We study the location of the partition function zeros in the complex β plane (Fisher’s Zeros) for SU(2) lattice gauge theory on L4 lattices. We discuss recent attempts to locate complex zeros for L = 4 and 6. We compare results obtained using various polynomial approximations of the logarithm of the density of states and a straightforward MC reweighting. We conclude that the method based on a c...
متن کاملOptimizing Teleportation Cost in Multi-Partition Distributed Quantum Circuits
There are many obstacles in quantum circuits implementation with large scales, so distributed quantum systems are appropriate solution for these quantum circuits. Therefore, reducing the number of quantum teleportation leads to improve the cost of implementing a quantum circuit. The minimum number of teleportations can be considered as a measure of the efficiency of distributed quantum systems....
متن کاملAndreev probe of persistent current states in superconducting quantum circuits.
Using the extraordinary sensitivity of Andreev interferometers to the superconducting phase difference associated with currents, we measure the persistent current quantum states in superconducting loops interrupted by Josephson junctions. Straightforward electrical resistance measurements of the interferometers give a continuous readout of the states, allowing us to construct the energy spectru...
