Quantum Random Access Memory [PDF]
Physical Review Letters, 2008 A random access memory (RAM) uses n bits to randomly address N=2^n distinct memory cells. A quantum random access memory (qRAM) uses n qubits to address any quantum superposition of N memory cells. We present an architecture that exponentially reduces the requirements for a memory call: O(log N) switches need be thrown instead of the N used in ...

On multiple access random medium access control [PDF]
2009 IEEE International Symposium on Information Theory, 2009 In this paper, we develop a new class of medium access control protocol, which allows each user to transmit at different data rates chosen randomly from an appropriately determined set of rates. By using successive interference cancellation, multiple packets can be received simultaneously.

Resource Allocation in 5G Cellular IoT Systems with Early Transmissions at the Random Access Phase [PDF]
SensorsWhile the market for massive machine type communications (mMTC) is evolving at an unprecedented pace, the standardization bodies, including 3GPP, are lagging behind with standardization of truly 5G-grade cellular Internet-of-Things (CIoT) systems.

Coded random access: applying codes on graphs to design random access protocols [PDF]
IEEE Communications Magazine, 2015 The rise of machine-to-machine communications has rekindled the interest in random access protocols as a support for a massive number of uncoordinatedly transmitting devices. The legacy ALOHA approach is developed under a collision model, where slots containing collided packets are considered as waste.

Collision Resolution for Random Access [PDF]
IEEE Transactions on Wireless Communications, 2022 As a building block toward a simple and scalable solution for massive random access, we introduce collision-resolution algorithms using successive interference cancellation (SIC) based on the received signals, with no need for any coordination or codebook differentiation. We first consider two-user multiple access with the ZigZag algorithm.

Random access parallel microscopy
eLife, 2021 We introduce a random-access parallel (RAP) imaging modality that uses a novel design inspired by a Newtonian telescope to image multiple spatially separated samples without moving parts or robotics. This scheme enables near-simultaneous image capture of

Random Power Back-Off for Random Access in 5G Networks
IEEE Access, 2021 In the massive Machine Type Communications (mMTC) scenario of the 5G network, a huge number of devices communicate with each other. The massive access requests will cause frequent access collisions, which will reduce the efficiency of Random Access (RA ...
