Quantum computing and artificial intelligence are no longer separate experiments they’re converging into a single capability stack. Applied Quantum Computing and AI (often called Quantum AI or quantum machine learning) focuses on using quantum principles and hardware to solve real-world problems in optimization, simulation, and advanced AI workflows.
At Varsity by InterviewBit, this category brings together courses, tutorials, and in‑depth articles that help engineers, data scientists, and tech leaders understand where quantum + AI creates real value today and how to build skills for the next decade.
Quantum money is a banknote that carries a sequence of quantum states alongside its serial number, and physics forbids anyone from copying those states perfectly. Stephen Wiesner proposed it around 1969–70. It was published in 1983, and it has never…
Quantum AI is the overlap between quantum computing and artificial intelligence. It is an active research field not a mature, widely deployed technology. This guide explores how the two fields are converging, the research behind their progress, current limitations, and…
Quantum technology is an emerging field of science and engineering that uses the principles of quantum mechanics to build technologies with capabilities beyond conventional systems. From ultra-precise sensors and secure communication networks to processors that could solve specialised problems beyond…
Quantum machine learning is the use of quantum computers to run part of a machine learning workflow, usually one specific step rather than the whole pipeline. It’s a research field today, not a production technology, and nothing in this article…
What Is Qiskit? Qiskit is IBM’s free, open-source Python toolkit for building quantum circuits and running them on simulators or on IBM’s real quantum computers. You don’t need a physics degree or a lab , just Python and a browser.…
Search for quantum computing applications and you’ll get a dozen near-identical lists: drug discovery, finance, logistics, AI, weather. What almost none of those lists tell you is which of those are actually running today, which are pilots, and which are…
Quantum error correction is the set of techniques that let a quantum computer stay reliable even though every qubit inside it is constantly drifting out of the state it’s supposed to hold. It sounds like a hardware detail. It’s actually…
What is Grover’s algorithm? Grover’s algorithm is a quantum algorithm for searching an unstructured space of N possibilities. It finds a marked item in roughly √N steps, where a classical brute-force search needs about N checks on average. That’s a…
Quantum key distribution (QKD) is a method of sharing a secret encryption key between two parties using individual particles of light, where the laws of physics, not the difficulty of a maths problem make an undetected eavesdropper impossible. Intercepting the…
If you searched for “quantum gates” expecting AND, OR, and NOT , classical logic gates and transistors, you’re in the right place, but the concept is different. Quantum gates are the quantum computing equivalent: operations that change the state of…
