Magic state distillation with low space overhead and asymptotic input count
Disclosed herein are example embodiments of protocols to distill magic states for T-gates. Particular examples have low space overhead and use an asymptotically optimal number of input magic states to achieve a given target error. The space overhead, defined as the ratio between the physical qubits to the number of output magic states, is asymptotically constant, while both the number of input magic states used per output state and the T-gate depth of the circuit scale linearly in the logarithm of the target error. Unlike other distillation protocols, examples of the disclosed protocol achieve this performance without concatenation and the input magic states are injected at various steps in the circuit rather than all at the start of the circuit. Embodiments of the protocol can be modified to distill magic states for other gates at the third level of the Clifford hierarchy, with the same asymptotic performance. Embodiments of the protocol rely on the construction of weakly self-dual Calderbank-Shor-Steane codes (“CSS codes”) with many logical qubits and large distance, allowing one to implement control-Swaps on multiple qubits. This code is referred to herein as the “inner code”. The control-Swaps are then used to measure properties of the magic state and detect errors, using another code that is referred to as the “outer code”. Alternatively, one can use weakly-self dual CSS codes which implement controlled Hadamards for the inner code, reducing circuit depth. Several specific small examples of this protocol are disclosed herein. |

A method of marking and authenticating a manufactured item, comprising providing the manufactured item with a visible anti-counterfeiting indicium, marking with marking means the manufactured item with a visible alphanumeric string, marking with marking means the manufactured item with visible marking time data, and transmitting with data transmission and control means marking time data marked on the manufactured item and the alphanumeric string marked on the manufactured item. The method further comprises with computer database control means, receiving the transmitted marking time data and the transmitted alphanumeric string and storing in association in a database marking time information corresponding with the received marking time data marked on the manufactured item and alphanumeric information corresponding with the received alphanumeric string marked on the manufactured item. The method further comprises checking authenticity of the anti-counterfeiting indicium provided on the manufactured item, interrogating the database with the alphanumeric string read from the manufactured item to obtain marking time information for the manufactured item, and comparing the marking time information with marking time data read from the manufactured item to determine if they match. The method comprises determining the manufactured item as authentic if criteria are met, the criteria including that the checking step reveals an authentic anti-counterfeiting indicium and the comparing step determines a match. |

Determining payment details based on contextual and historical information
A computing system may be configured to determine payment details for funds transfers from unstructured sets of data. The system may maintain historical transaction information associated with each of a plurality of users. The system may receive data associated with a transaction. The system may identify a user associated with the data, wherein the user is one of the plurality of users. The system may determine, based on contextual information of the data and the historical transaction information associated with the user, payment details about the transaction. The payment details may include a payment amount and one or more recipients. The system may execute a funds transfer for the payment amount from a source account associated with the user to one or more destination accounts associated with the one or more recipients. |

Determining implicit transaction consent based on biometric data and associated context data
The disclosure facilitates a transaction by determining implicit consent for a transaction from a user by a wearable computing device. A request to complete the transaction is received, biometric data associated with the user is collected, and context data associated with the biometric data is received. In response to the request to complete the transaction, weighted values of the biometric data and the context data are generated based on defined consent rules. Upon the generated weighted values satisfying one or more consent thresholds, implicit consent is determined for the transaction from the user, whereby completion of the transaction is enabled. Accurately determining implicit consent of a user for a transaction based on the user's biometric data streamlines the transaction process into an efficient, user-friendly experience for the user while maintaining the security of the user's identity and account information. |

Enhanced security credit card system
A system for enhanced security credit card has rechargeable battery, memory, processor, LCD display, thumbprint pad, magnetic swipe strip, multi-pin connector and USB port. The card is activated by the thumbprint of an authorized user, thereby turning on the blank LCD display to show a card number, expiration date, and CVV value. Additionally, the multi-pin connector is activated and inserted into credit card processing machine connector. This connection uploads the ‘PIN value, photograph and credit limit of the user on the processing machine display, verifying the user's identity and authorizing the credit card purchase. The use of a magnetic strip for credit card purchase also requires a ‘PIN’ value, which is provided by insertion of a thumbprint activated credit card multi-pin connector. The enhanced security is provided by thumbprint activation, blank LCD display of the credit card number, expiration date and CVV value, insertion of the multi-pin connector and visual verification of the card holder with a photograph of the user. |

System and method for dynamically partitioning a postage evidencing system
A postage evidencing system for tracking postage amounts for multiple users comprising at least two register set partitions is disclosed. Each of the partitions includes an ascending register holding a number representing a value of postage that can be evidenced by the device, a descending register holding a number representing a value of postage that has been previously evidenced by the device, and an identification representing a source of mail pieces that are evidenced with postage from the partition. A security module limits access to the partitions and registers. The identifier for a selected partition is printed on mail pieces as part of an Information Based Indicia (IBI) to identify the source of the mail pieces. |
