RC on Data Scence and Quantum Computing - Test

What is the fundamental unit of quantum information?

• Byte

• Bit

• Qubit

• Quantum gate

In quantum computing, superposition refers to:

• The ability to be in multiple states at once

• The ability to teleport information

• The process of measuring quantum states

• The destruction of quantum information

Which of the following gates is unique to quantum computing?

• XOR gate

• NAND gate

• Hadamard gate

• OR gate

Quantum entanglement means:

• Two qubits are isolated from each other

• One qubit is in a superposition state

• Two qubits are correlated such that the state of one depends on the state of the other, regardless of distance

• Qubits randomly change their state

In quantum mechanics, Heisenberg's Uncertainty Principle states that:

• We cannot simultaneously know both the energy and time of a quantum system

• We can measure both position and momentum exactly at the same time

• We can never know anything about quantum systems

• Qubits can only exist in a single state at any given time

Which of the following is a major challenge in building quantum computers?

• Power consumption

• Speed of computation

• Quantum decoherence

• Large memory requirements

The famous algorithm proposed by Peter Shor in quantum computing is used for:

• Factoring large integers

• Sorting large datasets

• Searching unsorted databases

• Solving linear equations

Grover's algorithm provides a quadratic speedup for which type of problem?

• Factoring large numbers

• Simulating quantum systems

• Database search

• Matrix inversion

What is the primary difference between classical bits and qubits?

• Bits can represent 1 or 0, while qubits can represent both 1 and 0 simultaneously

• Bits can exist in superposition, while qubits cannot

• Bits are based on quantum mechanics, while qubits are not

• There is no difference between bits and qubits

In quantum computing, a "quantum gate" is:

• A physical door leading to a quantum lab

• An operator that performs a specific operation on qubits

• A classical computing instruction set

• The output state of a quantum computer
