Quantum networks for computation

(My Edit of the following Paragraph) Networked Quantum Computing or Distributed Quantum[1] computing works by linking multiple quantum processors through a quantum network by sending qubits in-between them. Doing this creates a quantum computing cluster and therefore creates more computing potential. Less powerful computers can be linked in this way to create one more powerful processor. This is analogous to connecting several classical computers to form a computer cluster in classical computing. Like classical computing this system is scale-able by adding more and more quantum computers to the network. Currently quantum processors are only separated by short distances.

(Original Paragraph)In the domain of quantum computing, being able to send qubits from one quantum processor to another allows them to be connected to form a quantum computing cluster. This is often referred to as networked quantum computing, or distributed quantum computing. Here, several less powerful quantum processors are connected together by a quantum network to form one much more powerful quantum computer. This is analogous to connecting several classical computers to form a computer cluster in classical computing. Networked quantum computing offers a path towards scalability for quantum computers, since more and more quantum processors can naturally be added over time to increase the overall quantum computing capabilities. In networked quantum computing, the individual quantum processors are typically separated only by short distances.

Applications

Quantum networks can also be used to aid in secure communications.

Quantum Networks can be used in quantum communications to aid in jamming communication lines. This can be done in several different ways; spot jamming, sweep jamming, and barrage jamming. Spot jamming is when the attacker fully attacks one frequency that the enemy used with the same modulation only with more power. Sweep jamming is similar to spot jamming except it switches rapidly from one frequency to another in rapid succession. Barrage jamming is when an attacker attacks any frequencies at one time, but as the range grows the ability for to jam decreases.

Quantum Networks can also be used to protect against jamming. A user can use a Quantum Network by using Frequency-Hopping Spread Spread Spectrum(FHSS). This method is currently used by the United States army. In this method the user hops from frequency to frequency many times a second so that it is hard for an attacker to keep up and successfully attack the user. Direct Sequence Spread Spectrum (DSSS) this works by applying a Quantum operator to the system and then freely transmitting the information over the frequencies because an attacker cannot read the information without knowing the key (operator). These two techniques can be used together to produce a more secure communications system.

Starting Paragraph

Quantum networks form an important element of quantum computing and quantum communication systems. Quantum networks facilitate the transmission of information in the form of quantum bits, also called qubits, between physically separated quantum processors. A quantum processor is a small quantum computer being able to perform quantum logic gates on a certain number of qubits. Quantum networks work in a similar way to classical networks. The main difference, as will be detailed more in later paragraphs, is that Quantum networking like quantum computing is better at solving certain problems, such as modeling quantum systems.
