Superposition
How do qubits differ from classical bits?
Qubits can exist in a combination of states, while classical bits can only be 0 or 1
What is the significance of quantum computers tapping into the quantum mechanical phenomenon?
Manipulating information and shedding light on processes of molecular and chemical interactions
What is entanglement in the context of quantum mechanics?
'The ability of a particle to instantaneously influence the behaviour of another with whom it had an earlier ‘interaction,’ even when they are separated by arbitrarily great distances'
Study Notes
Classical vs Quantum Computers
- Classical computers use bits to store and process information, whereas quantum computers use qubits (quantum bits).
- Qubits can exist in multiple states simultaneously, allowing for parallel processing and exponential scaling.
Quantum Mechanical Phenomenon
- Quantum particles can exist at multiple locations at the same time due to the phenomenon of superposition.
- Superposition enables qubits to process multiple possibilities simultaneously, making quantum computers more efficient.
Qubits vs Classical Bits
- Qubits can exist in multiple states (0, 1, and both 0 and 1 simultaneously) due to superposition, whereas classical bits can only be in one of two states (0 or 1).
- Qubits are highly sensitive to their environment and require careful control to maintain their state.
Significance of Quantum Computers
- Tapping into the quantum mechanical phenomenon allows quantum computers to solve certain problems much faster than classical computers.
- Quantum computers have the potential to solve complex problems that are currently unsolvable or require an impractical amount of time to solve.
Entanglement
- Entanglement is a phenomenon where two or more particles become connected, allowing their properties to be correlated regardless of distance.
- Entanglement enables qubits to be connected and processed simultaneously, further increasing the power of quantum computers.
