In Good Company
This company created the quantum chip "Willow", which contains ~100 qubits
What is Google?
The name of the quantum state where two qubits are maximally entangled
What is a Bell State?
The gate NAND is capable of producing all possible logical operations, a property known by this name
What is "logically complete" (or "logical completeness")?
This is the earliest QKD protocol, where each bit of the secret key is built by sending a random qubit to be measured
What is the BB84 protocol?
In 1927, the dual-slit experiment used electrons to demonstrate this quantum mechanical property
What is particle-wave duality?
This company introduced Majorana 1, the world's first quantum chip on February 19, 2025.
What is Microsoft?
Simulating a 5 qubit system requires this number of state amplitudes to be stored in memory
What is 25 (or 32)?
In its simplest implementation (least number of operations), a half adder consists of these two gates
This term refers to components that are not affected by radiation.
What is radiation-hardened?
This famous thought experiment typically used to describe quantum superposition was originally introduced as a challenge to said principle
What is the Schroedinger's cat thought experiment
This company is the first to sell a quantum computer, sold in 2011. It was a 128 qubit system sold to a defense contractor.
What is D-Wave?
This gate takes three inputs: two control qubits and one target qubit. If both control qubits are in the |1⟩ state, the gate flips the target qubit, otherwise does nothing
What is a Toffoli Gate?
The binary string 11101 represents this number in 2's complement
What is -3
This quantum gate keeps |0> to |0> and turns |+> to |->, |-> to |+>, |i> into |-i>, and |-i> into |i>
What is Pauli Z gate>
An intrinsic form of angular momentum carried by elementary particles
What is Quantum Spin?
This company is responsible for the creation of the quantum computing library "Qiskit"
What is IBM?
This object is the geometric model that represents the state of a qubit
What is a Bloch Sphere?
This circuit component is used to open and close electrical contacts based on electrical input.
What is a relay?
A single error event is referred to by this term
What is a bit-flip?
A mathematical description of a quantum state
What is a wave function?
This company uses cold nuetral atom arrays trapped with laser technology to implement a qubit
What is AtomQL (or Atom Computing)?
This logical gate acts on a single quibit and creates an equal superposition from an initialized <0| or <1| state.
What is the Hadamard Gate?
The binary string 11101 represents this number
What is 29
This term refers to the state operation shown below (assume the state is normalized):
(|0>+|1>) to (|0>-|1>) or visa versa
What is a phase flip?
This theorem states that no quantum superposition can be duplicated without destroying the original
What is the no-cloning theorem?
