Hur ser en kvantdator ut?
En kvantdator fungerar ungefär likadant, men med en central skillnad, att en och samma partikel kan vara både 1 och 0 samtidigt. Det kallas för en kvantbit, som alltså befinner sig i en sorts superposition, i enlighet med kvantmekanikens lagar.
Vad används en kvantdator till?
En kvantdator är oerhört kraftfull och välanpassad för att lösa vissa typer av matematiska beräkningar inom till exempel fysik, kemi, och molekylärbiologi, det vill säga beräkningar som växer exponentiellt.
What is quantum computing?
What is quantum computing? Quantum computing is a rapidly-emerging technology that harnesses the laws of quantum mechanics to solve problems too complex for classical computers. Today, IBM Quantum makes real quantum hardware -- a tool scientists only began to imagine three decades ago -- available to thousands of developers.
What problems can quantum computers solve?
Notably, quantum computers are believed to be able to quickly solve certain problems that no classical computer could solve in any feasible amount of time—a feat known as "quantum supremacy." The study of the computational complexity of problems with respect to quantum computers is known as quantum complexity theory .
What is qubit in quantum computing?
Qubit - The basic unit of information in quantum computing. A qubit represents a quantum particle in superposition of all possible states. Interference - Intrinsic behavior of a qubit due to superposition to influence the probability of it collapsing one way or another.
Will quantum computers ever be scalable?
Some researchers have expressed skepticism that scalable quantum computers could ever be built, typically because of the issue of maintaining coherence at large scales. Bill Unruh doubted the practicality of quantum computers in a paper published back in 1994.
