Going Quantum: The future of the internet ...

Einstein called it 'spooky action at a distance.' Engineers now use this phenomenon to build a physically unhackable internet.

Going Quantum: The future of the internet ...
#1about 2 minutes

Comparing classical computing with quantum superposition

Quantum computing uses qubits in superposition to evaluate multiple function inputs simultaneously, unlike sequential classical computation.

#2about 2 minutes

How to manipulate qubits with gates and measurements

Qubits are manipulated using unitary matrices as gates, but measurements introduce probabilistic behavior that collapses the quantum state.

#3about 4 minutes

Understanding quantum entanglement through a simple analogy

Entanglement creates a strong, non-classical correlation between spatially separated qubits, enabling applications like quantum secret sharing.

#4about 2 minutes

Exploring key applications of quantum technologies

Quantum technology has major applications in secure key exchange, breaking RSA with Shor's algorithm, sensor networks, and simulating complex chemical systems.

#5about 6 minutes

Overcoming distance with quantum repeaters and teleportation

The no-cloning theorem prevents simple signal amplification, so quantum repeaters use error correction or entanglement-based teleportation to transmit states over long distances.

#6about 3 minutes

Enabling distributed cloud computing with measurement

Measurement-based quantum computation uses highly entangled cluster states as a universal resource, allowing distributed data centers to combine their power.

#7about 3 minutes

Proposing a network stack for quantum communication

A proposed quantum network stack, analogous to the classical OSI model, defines layers to manage entanglement and connectivity across networks.

#8about 5 minutes

Addressing the open problems in building a quantum internet

Building a quantum internet requires solving major challenges in standardization, interoperability, scalability, fault tolerance, and developing new routing protocols for entanglement.
