Romania’s state-owned passenger railway operator CFR Călători has warned that insufficient public service compensation for ...

Duality operators in symmetric 1D quantum lattice models can be implemented as unitary quantum circuits with linear depth by extending the Hilbert space with ancillary degrees of freedom and ...

Fundamental to the theory of joint signal representations is the idea of associating a variable, such as time or frequency, with an operator, a concept borrowed from quantum mechanics. Each variable ...

Environment. Qiskit version: 1.2.4; Python version: 3.10; Operating system: macOS; What is happening? The way Operator.power works, it's strongly assuming that the internal matrix is unitary, because ...

But also, it may refer to Haco’s previous career: Unitary operators are used in describing a quantum state, which in itself is complicated and unpredictable — just like online content and humans.) ...

In quantum optics, unitary transformations of arbitrary states are evaluated by using the Taylor series expansion. However, this traditional approach can become cumbersome for the transformations ...

By applying quantum phase estimation to the unitary operators that compose the Hamiltonian operator, one can obtain estimates of the energy levels and the corresponding states of the system.
