Quantum superpositions and entanglement of quantum bits (qubits) make it possible to perform parallel computations.

But quantum superposition makes it possible with just one

For nearly a century, physicists have explained the peculiarities of their quantum properties — such as wave - particle duality and indeterminism — by invoking an entity called the wave function, which exists in a superposition of all possible states at once right up until someone observes it, at which point it is said to «collapse» into a single state.

In the quantum world, particles like photons spend most of their time in a bizarre condition called a superposition, meaning the particles exist in several possible states at once.

Schrödinger proposed his «cat» after debates with Albert Einstein over the Copenhagen interpretation, which Schrödinger defended, stating in essence that if a scenario existed where a cat could be so isolated from external interference (decoherence), the state of the cat can only be known as a superposition (combination) of possible rest states (eigenstates), because finding out (measuring the state) can not be done without the observer interfering with the experiment — the measurement system (the observer) is entangled with the experiment.

The idea of a particle existing in a superposition of possible states, while a fact of quantum mechanics, is a concept that does not scale to large systems (like cats), which are not indeterminably probabilistic in nature.

They start out in a quantum superposition of all possible solutions, and then they use entanglement and quantum interference to home in on the correct answer — processes that we do not observe in our everyday lives.

Unlike classical computer bits, which utilize a binary system of two possible states (e.g., zero / one), a qubit can also use a superposition of both states (zero and one) as a single state.

It's also possible to join the superposition states of many qubits.

Which of the two possible kinds of motion prevails in the end depends on the time delay between the two pulses and on the quantum phase of the superposition.

Quantum physics tells us that an object can be in all possible states simultaneously — superposition — until it is observed.

The Vienna team investigated the concept of quantum superposition — the idea that if we do not know what the state of an object is, it is actually in all possible states simultaneously, as long as we don't look to check.

In recent years we have seen extensive studies of different aspects of coherence and superposition, e.g. their possible (debated) role in biological systems, their experimental verification in double slit experiments with large molecules and also in their quantification in the framework of resource theories.

Again, superposition of this changing background climate on projections with high resolution models resolving the relevant process does give valuable insights of the possible changes in risks and vulnerability.

Moreover, epoch superposition analysis of Forbush decreases reveals no detectable albedo response to cosmic ray decreases, thereby placing an upper limit on the possible influence of cosmic ray variations on global albedo of 0.0029 per 5 % decrease.
