Quantum states
Quantum state ... In quantum physics, a quantum state is a mathematical entity that embodies the knowledge of a quantum system. Quantum mechanics specifies the ...
Quantum States: They represent the way quantum things are right now and how they might change.
In layman's term, what is a quantum state? - Quora
A quantum state is simply something that encodes the state of a system. The special thing about quantum states is that they allow the system to be in a few ...
Quantum mechanics describes the behaviour of matter and light at the atomic scale (i.e. at distances d ∼ 10−10m), where physical objects behave very ...
A quantum state is any possible state in which a quantum mechanical system can be. A fully specified quantum state can be described by a state vector, a ...
hilbert space - What is a quantum state? - Physics Stack Exchange
A quantum 'state' does not have different properties as such. It is a 'collection' of all the properties of the system you are describing.
Quantum state space - Wikipedia
A quantum state space is an abstract space in which different positions represent, not literal locations, but rather quantum states of some physical system.
PHYS771 Lecture 13: How Big are Quantum States? - Scott Aaronson
A quantum state is an exponentially long vector of amplitudes in more-or-less the same sense that a classical probability distribution is an exponentially long ...

Quantum States and Operators - Mihirsinh Chauhan
Quantum states are the building blocks of quantum mechanics, while operators allow us to manipulate and measure these states. Understanding ...
Quantum states and their relations - YouTube
There are several different words to describe a quantum state: superposition, pure, mixed and entangled. These terms are all concepts in ...
What does "quantum state" mean? : r/AskPhysics - Reddit
Quantum states are rays in a Hilbert space. They are a complete description of the particle. Any observable you could measure is encoded into ...
[quant-ph/0608142] The Learnability of Quantum States - arXiv
We show that for most practical purposes one can learn a state using a number of measurements that grows only linearly with n.
Quantum state over time is unique - Physical Review Link Manager
In this paper, we propose sets of operationally motivated axioms for quantum states over time alternative to the ones proposed by Fullwood and Parzygnat.

Quantum State - an overview | ScienceDirect Topics
Quantum state tomography is a process of reconstructing the state for a source of a quantum system by measurements on the system.
What's the difference between a pure and mixed quantum state?
A pure state is the quantum state where we have exact information about the quantum system. And the mixed state is the combination of probabilities.
