WebbThe ICM features automatic block transfer and evic-tion, and has been at the base of the vast literature on cache-oblivious algorithms, i.e., algorithms which run eﬃciently independently of the cache parameters (i.e., cache size and cache line size).

Quantum Teleportation begins with the fact that Alice needs to transmit ψ = α 0 + β 1 ψ = α 0 + β 1 (a random qubit) to Bob. She doesn't know the state of the qubit. For this, Alice and Bob take the help of a third party (Telamon). Telamon prepares a pair of entangled qubits for Alice and Bob. hello kitty sweaters for girls
