What is quantum physics?
Click to flip
Quantum physics is the branch of science that deals with discrete, indivisible units of energy called quanta as they apply to the properties of elementary particles.

What is a quantum?
Click to flip
A quantum is the minimum amount of any physical entity involved in an interaction.
Click to flip
What is superposition in quantum physics?
Click to flip
Superposition is a principle that states that a quantum system can exist in multiple states or realities at once until it is measured.
Click to flip
What is an example of quantum superposition?
Click to flip
An example of quantum superposition is Schrödinger's cat, a thought experiment where a cat in a box is simultaneously considered alive and dead until observed.
Click to flip
Define entanglement in the context of quantum physics.
Click to flip
Entanglement is a phenomenon where particles become correlated in such a way that the state of one particle instantly influences the state of another, regardless of distance.
Click to flip
What is a quantum state?
Click to flip
A quantum state is the state of an isolated quantum mechanical system, usually represented by a wave function.
Click to flip
Who is known as one of the founding fathers of quantum theory?
Click to flip
Max Planck is considered one of the founding fathers of quantum theory for his discovery of energy quanta.
Click to flip
What is Planck's constant?
Click to flip
Planck's constant is a fundamental constant that relates the energy carried by a photon to its frequency. It is approximately 6.626 x 10^-34 Js.
Click to flip
What does the Heisenberg Uncertainty Principle state?
Click to flip
The Heisenberg Uncertainty Principle states that it is impossible to know both the position and the momentum of a particle with absolute precision.
Click to flip
What does the concept of wave-particle duality explain?
Click to flip
Wave-particle duality explains that every particle or quantum entity exhibits both wave and particle properties.
Click to flip
What experiment demonstrates the wave nature of electrons?
Click to flip
The double-slit experiment demonstrates the wave nature of electrons, showing interference patterns typical of waves.
Click to flip
What is a quantum leap?
Click to flip
A quantum leap is a sudden transition of an electron from one energy level to another within an atom.
Click to flip
Name a technology that utilizes principles of quantum physics.
Click to flip
MRI machines use principles of quantum physics, particularly nuclear magnetic resonance.
Click to flip
What is quantum tunneling?
Click to flip
Quantum tunneling is a quantum phenomenon where particles pass through a potential barrier that they classically shouldn't be able to.
Click to flip
How does quantum computing utilize the principles of quantum physics?
Click to flip
Quantum computing uses quantum bits or qubits to perform calculations based on the principles of superposition and entanglement, which allows for potentially vast computational power.
