Methods of digital communication utilizing entangled qubits are disclosed. The communication methods exploit selective entanglement swapping to transfer an entangled state between a sending device and a receiving device. Each device includes pairs of qubits that are independently entangled with pairs of qubits in the other device. By selectively entangling the qubits within a pair in the sending device, the qubits of the corresponding pair in the receiving device also are selectively entangled. When the qubits are entangled, they are projected onto a particular entangled state type. Though no information may be transferred through selective entanglement of one qubit pair, the disclosed methods determine whether a set of pairs of qubits are entangled by determining whether the distribution of pairs is a correlated or uncorrelated distribution (a probabilistic approach) and transform the distribution type to a classical bit of data to transfer classical bits in a qubit-efficient approach.

Digital communication systems utilizing entangled qubits are disclosed. The disclosed systems and component sending devices and receiving devices exploit selective entanglement swapping to transfer an entangled state between the sending device and the receiving device. Each device includes pairs of qubits that are independently entangled with pairs of qubits in the other device. By selectively entangling the qubits within a pair in the sending device, the qubits of the corresponding pair in the receiving device also are selectively entangled. When the qubits are entangled, they are projected onto a particular entangled state type. Though no information may be transferred through selective entanglement of one qubit pair, systems of the present disclosure determine whether a set of pairs of qubits are entangled by determining whether the distribution of pairs is a correlated or uncorrelated distribution (a probabilistic approach) and transform the distribution type to a classical bit of data.

Systems and methods for digital communication utilizing entangled qubits are disclosed. The disclosed systems and methods exploit selective entanglement swapping to transfer an entangled state between sites. Each site includes pairs of qubits that are independently entangled with pairs of qubits at the other site. By selectively entangling the qubits within a pair at one site, the qubits of the corresponding pair at the other site also are selectively entangled. When the qubits are entangled, they are projected onto a particular entangled state type. Though no information may be transferred through selective entanglement of one qubit pair, systems and methods of the present disclosure determine whether a set of pairs of qubits are entangled by determining whether the distribution of pairs is a correlated or uncorrelated distribution (a probabilistic approach) and transform the distribution type to a classical bit of data.

An article of headwear ( ), preferably of moisture absorbent cloth, having two narrow end sections ( ) and a wide middle section ( ) for covering the head and neck of a wearer. The inner side ( ) of the middle section ( ) contains a pocket ( ) near the bottom ( ) for holding thermal matter ( ), such as frozen liquid or heat pads. An optional semi-circular headband ( ) on the inner side ( ) of the middle section ( ) above the pocket ( ) may assist in placing and holding the headwear to a forehead on a person. An optional visor ( ) extending from the top portion ( ) of the headwear is also provided. The end sections may serve as handles to be held by the hands. Various other fastening means ( ) have been provided for securing the headwear to the head of a wearer. The outside ( ) of the headwear may also serve as a medium for advertising ( ). Cooling relief and protection from the sun, as well as perspiration absorbency, during hot and humid weather, or, alternatively, warming during cold weather is provided by this invention.
