Quantum error correction takes advantage of entanglement to protect information from environmental disturbances, ensuring that the environment cannot learn anything about the protected information.

To protect privacy in a quantum computing era, we need to develop new cryptographic protocols that are resistant to quantum attacks, as well as explore quantum communication for secure information transfer.

Quantum entanglement is a key property that allows information to be stored in the correlations between parts of a quantum system, making it difficult to access that information by examining individual parts.

Quantum computers pose a risk to current encryption schemes, particularly public key cryptography, which relies on the difficulty of certain computational problems.

In the mid-90s, we developed quantum error correction theory, which encodes quantum states in a way that protects them from environmental interactions, ensuring they remain robust.

Network approaches to quantum computing enable any qubit to link with any other qubit, enhancing connectivity and power, despite the increased risk of errors if not managed correctly.

The key to effective quantum computing is ensuring qubits interact as desired, rather than just focusing on increasing coherence times.

Quantum entanglement means that when two particles are entangled, measuring one instantly determines the state of the other, regardless of the distance between them.

Using multiple links in quantum communication can improve the quality of information transfer, similar to how conventional technology compensates for weak signals by requesting data multiple times to ensure accuracy.
