Quantum vs Classical Notions of Reality
The contrast between quantum and classical notions of reality is one of the most profound paradigm shifts in the history of science. While classical physics, built by Newton, Maxwell, and….

Quantum Word Embeddings
Word embeddings are a foundational concept in Natural Language Processing (NLP), enabling models to represent words as dense vectors in high-dimensional space. These vectors capture semantic relationships such as similarity,….
Quantum Coherence in Optics
To understand quantum coherence, we need to first explore classical coherence. Coherence is a term that describes how predictably waves behave over time and space. If two light waves are….
Quantum Oblivious Transfer
Quantum Oblivious Transfer (QOT) is a powerful cryptographic protocol rooted in quantum mechanics. It allows a sender (let’s say Alice) to send information to a receiver (Bob) in a special….
Quantum Coin Flipping
Quantum Coin Flipping (QCF) is a cryptographic protocol that allows two parties—who don’t trust each other—to agree on a random binary outcome (heads or tails, or 0 or 1), using….
Quantum Walk Algorithms
Quantum Walk Algorithms are quantum versions of random walks, which are processes that involve taking steps from one point to another in a randomized way — like flipping a coin….
Simon’s Algorithm
Simon’s Algorithm is a quantum algorithm that solves a very specific type of problem exponentially faster than any classical algorithm can. It was proposed by Daniel Simon in 1994 and….
Deutsch-Jozsa Algorithm
1. What Is the Deutsch-Jozsa Algorithm? The Deutsch-Jozsa algorithm is one of the earliest examples of how quantum computing can outperform classical computing — and it does so dramatically. It….
Quantum Fourier Transform
1. What Is the Fourier Transform (Intuition First)? Before diving into the quantum version, let’s first understand the basic idea of a Fourier Transform. Imagine you’re listening to music. Although….
Quantum Gates and Circuits
In classical computing, we use circuits made from logic gates like AND, OR, and NOT to process information using bits (which are either 0 or 1). Quantum computing is similar….
