Questions and answers designated by tag: Unitary Operators

The hermitian conjugation of the unitary transformation is the inverse of this transformation?

Sunday, 05 May 2024 by dkarayiannakis

In the realm of quantum information processing, unitary transformations play a pivotal role in the manipulation of quantum states. Understanding the relationship between unitary transformations and their Hermitian conjugates is fundamental to grasping the principles of quantum mechanics and quantum information theory. A unitary transformation is a linear transformation that preserves the inner product of

The Hilbert space of a composite system is a vector product of Hilbert spaces of the subsystems?

Saturday, 04 May 2024 by dkarayiannakis

In quantum information theory, the concept of composite systems plays a important role in understanding the behavior of multiple quantum systems. When considering a composite system composed of two or more subsystems, the Hilbert space of the composite system is indeed a vector product of the Hilbert spaces of the individual subsystems. This concept is

Prove that a unitary transform preserves the inner product between two sets of vectors.

Sunday, 06 August 2023 by EITCA Academy

A unitary transform is a fundamental concept in quantum information processing that plays a important role in preserving the inner product between sets of vectors. In order to prove this, we need to understand the properties of unitary transforms and how they preserve the inner product. A unitary transform is a linear operator that preserves

Why is the sy – state considered to have complete rotational invariance under all complex rotations?

Sunday, 06 August 2023 by EITCA Academy

The Bell state, also known as the maximally entangled state, is an important concept in the field of quantum information. It is a two-qubit state that exhibits a unique property known as rotational invariance under all complex rotations. This property makes it a valuable resource for various quantum information processing tasks, such as quantum teleportation
