Trading t-gates for qubits in arbitrary state and unitary synthesis
Efficient synthesis of arbitrary quantum states and unitaries from a universal fault tolerant gate-set (e.g., Clifford+T) is a goal in quantum computation. As physical quantum computers are fixed in size, all available qubits should be used if it minimizes overall gate counts, especially that of the expensive T-gates. In this application, a quantum algorithm is described for preparing any dimension-N quantum state specified by a list of N classical numbers, that realizes a trade-off between space and T-gates. Example embodiments exploit (λ) ancilla qubits, to reduce the T-gate cost to 𝔒 ( N λ + λlog 2 N ϵ ) . Notably, this it proven to be optimal up to logarithmic factors for any λ=o(√{square root over (N)}) through an unconditional gate counting argument. Though (N) Clifford gates are always required, only (√{square root over (N)}) T-gates are needed in the best case, which is a quadratic improvement over prior art. Similar statements are provien for unitary synthesis by reduction to state preparation. |

Techniques for updating big data tables using snapshot isolation
Methods, systems, and computer program products are described herein for updating big data tables using snapshot isolation. The tables may store data (e.g., as data objects) collected from different users. The tables are stored in a first data store. The data's metadata is stored in a second data store. The metadata comprises version numbers for the objects that correspond to a consistent version thereof. When an update process for the table is initiated, a coordinator locks the metadata, and. the objects are updated. If the update to the objects is successful, the coordinator commits the updates and obtains the new version numbers of the objects. If all the commits are successful, the coordinator atomically updates the metadata with the new version numbers and releases the lock. However, if a commit to an object is unsuccessful, a subsequent process rolls back the committed objects to the version numbers specified by the metadata. |

Self-learning disaster-avoidance and recovery
A machine-learning mechanism of a disaster-avoidance system trains a knowledgebase to associate characteristics of a data-center component with corresponding degrees of vulnerability to failure and with remedial steps that may be undertaken to avoid failure or to reduce adverse effects of a failure. This training is performed as a function of inferences derived from historical records and from extrinsic information sources. The historical records identify past failures of similar components, component characteristics associated with past failures, and results of remedial procedures undertaken in response to past failures or to previous occurrences of the characteristics. The extrinsic sources identify the current existence of external conditions known to be associated with past failures. When a component's total degree of vulnerability exceeds a predefined threshold value, the system assembles a subset of that component's remedial steps into a remedial procedure and directs downstream modules or administrators to implement the procedure. |

Controlling access by a network interface
A server computer toggles between a protected mode and an unprotected mode. In the protected mode, users are unable to access configuration information due to a Base Address Register (BAR) being cleared. However, a service provider can access a Trusted Platform Module (TPM) through an Application Program Interface (API) request. In an unprotected mode, the BAR is programmed so that users can access the configuration information, but the TPM is blocked. Blocking of the TPM is achieved by changing a configuration file, which changes an overall image of the card. With the modified image not matching an original image, the TPM blocks access to data, such as encryption keys. Separate interfaces can be used for user access (PCIe) and service provider access (Ethernet) to the server computer. The server computer can then be toggled back to the protected mode by switching the configuration file to the original configuration file. |

Enabling tenant administrators to initiate request driven peak-hour builds to override off-peak patching schedules
A system enables initiation of request driven peak-hour builds to override “off-peak” patching schedules for updating server applications.

Mechanical-chemical energy storage
This invention generally relates to mechanical-chemical energy storage. In particular, the invention relates to a mechanical-chemical energy storage system that stores energy by simultaneously compressing a gas to a higher enthalpy state and recovering the heat of compression by driving a somewhat reversible chemical reaction. The heat energy in the chemical reaction is then recovered while the gas is expanding to a lower enthalpy state. |

Sintering furnance
Disclosed is a sintering furnace comprising a furnace body and a lifting device, wherein the furnace body comprises a furnace chamber (10) and a furnace mouth (20), the furnace chamber (10) is connected with the furnace mouth (20), wherein the sintering furnace further comprises a sealing member (30) provided at the lifting device; when the sintering furnace is in a loading or unloading condition, the sealing member (30) blocks the furnace mouth (20). When the sintering furnace is in an unloading condition, the sealing member (30) can block the furnace mouth (20), the furnace chamber (10) does not contact with the outside directly, thus the temperature in the furnace chamber (10) will not drop sharply, and the service life of the sintering furnace will be increased. |
