Keep pulling the thread on Albert Einstein.
When electrons are fired through a double slit, they strike the screen as discrete particles but collectively build up an interference pattern, demonstrating wave-particle duality.
The act of observing which slit an electron passes through causes its wave nature to collapse, destroying the interference pattern in a process called decoherence.
Maintaining quantum coherence is the primary challenge in building quantum hardware, as any environmental interaction can destroy the computation.
Quantum computers have the potential to solve problems that would take a modern supercomputer thousands of years to complete.
In superconducting qubits, a Josephson junction is added to the LC circuit to create unevenly spaced energy levels, allowing for the isolation of the 0 and 1 qubit states.
The farthest distance achieved for Quantum Key Distribution (QKD) is claimed to be 10,000 kilometers between China and Africa via satellite.
In 1900, Max Planck proposed that energy is delivered in discrete packets called quanta.
In 1913, Niels Bohr proposed that electrons in an atom inhabit specific, fixed orbits corresponding to discrete energy levels.
Louis de Broglie proposed that solid matter, such as electrons, also behaves like waves.
The qubit, a unit of quantum information based on superposition, was discovered in 1995.
In 1926, Erwin Schrödinger introduced the wave equation, which is the quantum physics equivalent of Newton's laws.
Superconducting quantum computers must be cooled to approximately 15 millikelvin using a dilution refrigerator.
