Quantum Algorithms An algorithm is a step-by-step procedure to perform a calculation, or a sequence of instructions to solve a problem, where each step can be performed on a computer. Therefore, an algorithm is a quantum algorithm when it can be performed on a quantum computer. In principle...
Quantum computing is advancing rapidly, with substantial investments and research pushing its potential to revolutionize industries. While classical computers might take years to solve complex computations, a quantum computer running Shor’s algorithm can accomplish the same task in mere hours. However, ...

Tying shoelaces.Tying shoelaces is another example of following an algorithm. For example, there are a finite number of steps that lead to a properly tied traditional shoelace knot, which is often referred to as the "bunny rabbit" or "loop, swoop and pull" knot. Facial recognition.Facial re...
Quantum error correction enables large quantum programs to complete without noise corrupting their output. At the end of a quantum program, the qubits in a QPU undergo readout. In some algorithms the result of this readout is probabilistic - sometimes requiring the algorithm to be repeated ...
History of quantum computing What is a qubit? What are the requirements to build a quantum computer? Understand quantum phenomena Related content Quantum computing holds the promise of solving some of our planet's biggest challenges - in the areas of environment, agriculture, health, energy, climat...
If there is a field of research considered to have revolutionary potential among scientists in the fields of computing and technology today, then quantum computing is at the top of the list worldwide – as one of the emerging key technologies of the 21st century. But how exactly is the opera...
NISQ machines are useful for quantum experimentation and algorithm development and have done much to advance the technology. However, they lack the scale to exceed the computational capabilities and practicality of classical computers -- a milestone calledquantum advantagethat is the holy grail of devel...
What is a qubit? A qubit is the basic unit of information in quantum computing. Qubits play a similar role in quantum computing as bits play in classical computing, but they behave very differently. Classical bits are binary and can hold only a position of 0 or 1, but qubits can hold...
