Enlargement of Calderbank-Shor-Steane quantum codes
It is shown that a classical error correcting code C = [n, k, d] which contains its dual, C⊥ ⊆ C, and which can be enlarged to C ′ = [n, k′ > k + 1, d′], can be converted into a quantum code of parameters [[n, k + k′ − n,min(d, d3d′/2e)]]. This is a generalisation of a previous construction, it enables many new codes of good efficiency to be discovered. Examples based on classical Bose Chaudhur...
متن کاملSecure Direct Communication Using Quantum Calderbank-Shor-Steane Codes
The notion of quantum secure direct communication (QSDC) has been introduced recently in quantum cryptography as a replacement for quantum key distribution, in which two communication entities exchange secure classical messages without establishing any shared keys previously. In this paper, a quantum secure direct communication scheme using quantum Calderbank-Shor-Steane (CCS) error correction ...
متن کاملEffect of ancilla’s structure on quantum error correction using the 7-qubit Calderbank-Shor-Steane code
In this work we discuss the ability of different types of ancillas to control the decoherence of a qubit interacting with an environment. The error is introduced into the numerical simulation via a depolarizing isotropic channel. The range of values considered are 10 -4 ≤ ε ≤ 10 for memory errors and 3. 10 -5 ≤ γ/7 ≤ 10 for gate errors. After the correction we calculate the fidelity as a qualit...
متن کاملLocal non–Calderbank-Shor-Steane quantum error-correcting code on a three-dimensional lattice
We present a family of non-Calderbank-Shor-Steane quantum error-correcting code consisting of geometrically local stabilizer generators on a 3D lattice. We study the Hamiltonian constructed from ferromagnetic interaction of overcomplete set of local stabilizer generators. The degenerate ground state of the system is characterized by a quantum error-correcting code whose number of encoded qubits...
متن کاملNoisy processing and distillation of private quantum States.
We provide a simple security proof for prepare and measure quantum key distribution protocols employing noisy processing and one-way postprocessing of the key. This is achieved by showing that the security of such a protocol is equivalent to that of an associated key distribution protocol in which, instead of the usual maximally entangled states, a more general private state is distilled. In ad...
