Alice, Bob, and Eve: How quantum technology can secure against adversaries
Quantum key distribution (QKD) offers a provably secure communication method that protects against potential quantum computer attacks on classical encryption. The technique uses quantum mechanics principles, specifically the Heisenberg uncertainty principle, to ensure uninterceptable communication between parties. QKD provides a robust alternative to traditional encryption methods that could be compromised by quantum computing technologies.

The current state of quantum cryptography, QKD, and the future of information security
Quantum key distribution (QKD) offers a provably secure communication method based on quantum physics principles. The technology leverages the Heisenberg uncertainty principle to create encryption keys that cannot be intercepted without detection. Commercial QKD systems are being developed to extend communication ranges and integrate with existing security infrastructure.

D-Wave, why all the controversy?
D-Wave's quantum computer uses quantum annealing architecture, specialized for solving optimization problems. Unlike universal quantum computers, it offers significant speed advantages for certain computational tasks but has limitations in quantum scaling and programmability. The computer can solve some optimization problems much faster than classical computers, though its applicability remains restricted to specific problem types.

Quantum paradoxes: Popping the bubble with Shor's algorithm
Quantum computers pose a significant threat to current cryptographic systems through Shor's algorithm, which can efficiently factor large prime numbers used in encryption. The algorithm leverages quantum mechanical principles and Fourier transforms to break RSA encryption by finding prime factors much faster than classical computers. Increasing investments in quantum technologies suggest that cryptographic systems may become vulnerable in the future as quantum computing capabilities advance.
