Quantum computing: Three of diamonds.
From DNA replication to satellite communication, identifying and fixing errors is an essential part of building robust large-scale systems. Common approaches to error correction make use of redundancy (encoding copies of information across more than one entity) and rely on the fact that multiple errors are less likely to occur than a single error. For error correction in quantum information pro...
متن کاملHardware Support for Hiding Cache Latency
As the decrease in processor cycle time continues to outpace the decrease in memory cycle time, even moderately sized on-chip caches may require several cycles of access time in the near future. This means that time is lost, even on a cache hit, if independent instructions cannot be scheduled after a read from memory. A novel hardware device is proposed that keeps track of the history of load i...
متن کاملHiding Quantum States in a Superposition
A method to hide certain quantum states in a superposition will be proposed. Such method can be used to increase the security of a communication channel. States represent an encrypted message will disappear during data exchange. This makes the message 100% safe under direct measurement by an eavesdropper. No entanglement sharing is required among the communicating parties.
متن کاملQuantum data hiding
We expand on our work on Quantum Data Hiding [1] – hiding classical data among parties who are restricted to performing only local quantum operations and classical communication (LOCC). We review our scheme that hides one bit between two parties using Bell states, and we derive upper and lower bounds on the secrecy of the hiding scheme. We provide an explicit bound showing that multiple bits ca...
متن کاملA quantum way to data hiding
Though security is nothing new, the way that security has become a part of our daily lives today is unprecedented. Today, steganography is most often associated with the high-tech variety, where data is hidden within other data in an electronic file. Steganography is hidden writing, whether it consists of invisible ink on paper or copyright information hidden in an audio or video file. This wor...
