Hypothesis

Researchers have built the first quantum computer that can not only be programmed, but, just like a regular computer, can actually be reprogrammed, too.

Context

Differences between Classical computers and quantum computers

Classical Computers

The Classical theory of computation is based on binary units of information called bits that can either been ‘1’ or ‘0’ and ‘true’ or ‘false’.

quantum computers

Quantum processors, on the other hand, are made of qubits, which can be ‘1’, ‘0’ or both at the same time.

Problem

While many groups have built small quantum computing devices in the past, most of these have only been hard-wired to solve a single problem, and any reprogramming requires complex physics.

Findings

This new device is different

Because it's easily reprogrammable, and it's already been shown to solve three algorithms in a single step, something that would require several operations for a normal computer to calculate.

Algorithms

The team reprogrammed the device to run three problems that quantum computers are known to be able to solve.

  • Quantum Fourier Transform algorithm (70 percent).
  • the Bernstein-Vazirani algorithm (90 percent successful)
  • the Deutsch-Jozsa algorithm (which it could complete with 95 percent success rate)
