Is there any alternative of quantum computing?

Meet The Memcomputer: The Brain-Like Alternative to Quantum Computing. This computer works like the brain: It stores and processes info simultaneously. For some computer scientists, the solution lies in building quantum computers—devices which take advantage of the inexplicable weirdness of atomic-level physics.

What is beyond quantum computer?

Beyond Quantum Computers are computers than can overcome the Church-Turing thesis (See the Wikipedia page with this name) and, more generally, can compute the truth value of propositions that are undecidable by a finite computation, or, equivalently, underivable in a finite number of steps from a fixed axiom system.

Is there a quantum theory?

To begin with, there’s no single quantum theory. There’s quantum mechanics, the basic mathematical framework that underpins it all, which was first developed in the 1920s by Niels Bohr, Werner Heisenberg, Erwin Schrödinger and others.

Is Quantum Science proven?

Predictions of quantum mechanics have been verified experimentally to an extremely high degree of accuracy. A fundamental feature of the theory is that it usually cannot predict with certainty what will happen, but only give probabilities.

Has a true quantum computer been built?

Big Blue has, for the first time, built a quantum computer that is not physically located in its US data centers. For the company, this is the start of global quantum expansion. Fraunhofer Institute have just unveiled the Quantum System One, the country’s first superconducting quantum computer built by IBM.

How far along are quantum computers?

How long until that future arrives? Most current quantum computers have around a hundred qubits at most. That might increase to a thousand or so over the next few years, but quantum computers that are actually useful are probably at least a decade away.

What are the limits of quantum computing?

Quantum computers are exceedingly difficult to engineer, build and program. As a result, they are crippled by errors in the form of noise, faults and loss of quantum coherence, which is crucial to their operation and yet falls apart before any nontrivial program has a chance to run to completion.

Why are there so few quantum algorithms?

The first possible reason is that quantum computers operate in a manner so different from classical computers that our techniques for designing algorithms and our intuitions for understanding the process of computation no longer work.
