Theoretically a large-scale quantum computer could break some widely used encryption schemes and aid physicists in performing physical simulations; however, the current state of the art is largely experimental and impractical, with several obstacles to useful applications.

Mar 18, 2025 · In theory, topological qubits could encode quantum information into the braiding pattern of “quasiparticles” that emerge from the collective behavior of individual particles such as electrons.

Dec 3, 2006 · Combining physics, mathematics and computer science, quantum computing and its sister discipline of have developed in the past few decades from visionary ideas to two of the most fascinating areas of quantum theory.

The goal of this thesis is to explore the fundamental knowledge base of quantum computation, to demonstrate how to extract the necessary design criteria for a functioning tabletop quantum computer, and to report on the construction of a portable NMR spectrometer which can characterize materials and hopefully someday perform quantum computation.

Quantum computing is an area of computer science focused on the development of computers based on the principles of quantum theory. Quantum computing uses the unique behaviors of quantum physics to solve problems that are too complex for classical computing.

Aug 5, 2024 · Quantum computing is an emergent field of cutting-edge computer science harnessing the unique qualities of quantum mechanics to solve problems beyond the ability of even the most powerful classical computers.

Jan 28, 2019 · WHAT IS QUANTUM COMPUTING? Quantum and classical computers both try to solve problems, but the way they manipulate data to get answers is fundamentally different. This section provides an explanation of what makes quantum computers unique by introducing two principles of quantum mechanics crucial for their operation, superposition and entanglement.

Caltech experts explain the science behind quantum computing in simple terms and outline what quantum computers could be used for.

Jul 29, 2024 · From Richard Feynman’s visionary lectures in the early 1980s to Google’s claim of quantum supremacy in 2019, we’ll trace the quantum computing journey and examine the technological advancements that have brought us to the brink of a new computing era.

Mar 12, 2025 · For decades, the theory of quantum computing has promised large speedups over classical algorithms for select tasks. Only in the last few years has this come to fruition, with a growing variety of quantum processing units (QPUs) performing computations faster than sophisticated classical approaches—these QPUs include photonic (1, 2), neutral-atom (3, 4), and superconducting (5 – 8) systems ...
