Entanglement Purification: Cleaning a Noisy Link
Entanglement purification turns several noisy entangled pairs into fewer better ones using local operations and classical communication. How it works.
Quantum Circuit Design: Algorithms and Compilers
How quantum circuits are designed and compiled: gate decomposition, qubit mapping, depth reduction, parallelization, synthesis and benchmarking.
Quantum Teleportation: What Is Actually Transferred
Quantum teleportation transfers a quantum state, not matter, and needs a classical signal, so nothing travels faster than light. How it works and is used.
Who Invented Quantum Physics? The People and Dates
Who created quantum physics: Planck, Einstein, Bohr, Heisenberg, Schrödinger, Dirac, Pauli, de Broglie, Born and others, with their key ideas.
Quantum Entanglement Theory, Explained Plainly
Quantum entanglement explained without jargon: its history, Einstein’s objections, Bell’s theorem, key experiments and uses in computing and cryptography.
Can Entanglement Be Used to Communicate?
Why entanglement cannot send information faster than light, and how it is still used in quantum key distribution, teleportation and quantum networks.
Quantum Gates Explained: The Basic Operations
What quantum gates are and how they act on qubits: single-qubit rotations, Hadamard, CNOT, Toffoli, unitary matrices and the quantum Fourier transform.
