53x01 Quantum Computing - The Foundation of Everything

Is light a particle? Is light a wave? Let's take a look at Thomas Young's famous double-slit experiment--creating those really super funky interference patterns you might remember from your high school physics classes.

Today we're exploring one of Albert Einstein's most controversial papers: his ideas on the photoelectric effect, which describes light as quanta (discrete packets of energy) instead of a classical wave. This new understanding of light helped Niels Bohr create a new model of the atom.

To understand the power and the challenges of the quantum computer, we have to spend a little more time watching the intense debates between Neils Bohr and Albert Einstein about the Uncertainty Principle. Can we really know the energy of a photon?

What happens when we can't link physical cause and effect between two actions? Well, quantum bits (or qubits) do this all the time. Let's look into how quantum entanglement can be used in computing.

Quantum computing isn't a replacement for classical computing... yet. Quantum decoherence happens when anything gets in the way of a qubit's job, so sterile low-temperature environments are an absolute necessity.

What does the quantum revolution mean today? We talk about quantum computing application possibilities in machine learning, cybersecurity, environmental science, and more.
