The means to perform quantum computation on logical information stored within the toric code has been considered, with the properties of the code providing fault-tolerance. It has been shown that extending the stabilizer space using 'holes', vertices or plaquettes on which stabilizers are not enforced, allows many qubits to be encoded into the ...
The toric code, and surface codes more generally, [1] are types of stabilizer codes considered very important for the practical realization of quantum information processing. Conceptual background [ edit ]
The ideas of stabilizer codes, CSS codes, and topological codes can be expanded into the 2D planar surface code, of which various types exist. [17]
Current estimates put the threshold for the surface code on the order of 1%, [8] though estimates range widely and are difficult to calculate due to the exponential difficulty of simulating large quantum systems.
In this code, 5 physical qubits are used to encode the logical qubit. [2] With X {\displaystyle X} and Z {\displaystyle Z} being Pauli matrices and I {\displaystyle I} the Identity matrix , this code's generators are X Z Z X I , I X Z Z X , X I X Z Z , Z X I X Z {\displaystyle \langle XZZXI,IXZZX,XIXZZ,ZXIXZ\rangle } .
The second generation added a 55 degrees angle position which according to Microsoft makes the device more comfortable to type on the lap. The Surface 3 features three angle positions: 22, 44, and 60 degrees. The Surface Pro 3 is the first device to have a continuous kickstand that can be set at any angles between 22 and 150 degrees.

SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by staffed and automated weather stations. SYNOP reports are typically sent every six hours by Deutscher Wetterdienst on shortwave and low frequency using RTTY .
