Quantum Computing Basics

What is the name of the phenomenon where a qubit can be in multiple states simultaneously?

• • Entanglement

• • Superposition

• • Teleportation

• • Quantum tunneling

What visualization tool helps us see the state of a single qubit?

• • A microscope

What's the difference between a regular bit and a qubit?

• • A qubit is faster

• • A qubit can be 0, 1, or both

• • A qubit is a different color

• • A qubit is used in regular computers, a bit is in quantum computers

What does a quantum gate do?

• • Lets information in or out of a quantum program

• • Changes the state of a qubit

• • Connects the quantum computer to the internet

• • Makes a beeping noise

To run a program on a quantum computer, you would design a:

• • Quantum website

• • Quantum circuit

• • Quantum drawing

• • Quantum email

Which of the following best describes decoherence?

• • The phenomenon where a quantum system loses its quantum properties, due to interactions with the external environment.
