Surface code implementation of block code state distillation
State distillation is the process of taking a number of imperfect copies of a particular quantum state and producing fewer better copies. Until recently, the lowest overhead method of distilling states produced a single improved [formula: see text] state given 15 input copies. New block code state distillation methods can produce k improved [formula: see text] states given 3k + 8 input copies, ...
متن کاملImplementation of Polar Code Decoders
In this report, we review the construction of polar codes and we briefly present the main results that lead to the conclusion that polar codes are capacity achieving over binaryinput discrete memoryless channels. Moreover, we discuss a more sophisticated variant of successive cancellation decoding, namely list successive cancellation decoding, that aims to improve the finite-length performance ...
متن کاملSurface code quantum communication.
Quantum communication typically involves a linear chain of repeater stations, each capable of reliable local quantum computation and connected to their nearest neighbors by unreliable communication links. The communication rate of existing protocols is low as two-way classical communication is used. By using a surface code across the repeater chain and generating Bell pairs between neighboring ...
متن کاملFinite-State Code Generation
This paper describes GBURG, which generates tiny, fast code generators based on finite-state machine pattern matching. The code generators translate postfix intermediate code into machine instructions in one pass (except, of course, for backpatching addresses). A stack-based virtual machine-known as the Lean Virtual Machine (LVM)-tuned for fast code generation is also described. GBURG translate...
متن کاملPerformance of Reed - Solomon Block Turbo Code
11, we present two methods for the constuction codes and in section 111, we describe the soft decoding algorithm and give some results of RS soft decoding. In section IV, we give the soft decision algorithm derived from the theoretical Log-Likelihood-Ratio and in section V we describe the iterative algorithm for decoding RS product codes. Section VI and VI1 are dedicated to simulation results o...
