Abstract: A method of renting rentable items using NFTs receives a request from an owner to list a rentable item for rent, causes a distributed ledger system to mint an inheritable rental NFT, and assign the rental NFT to the owner. The method lists the item for rent, receives a request from a renter to rent the item for a first set of time durations, and causes the distributed ledger system to mint a first set of child rental NFTs, where each child rental NFT is associated with a time duration in the first set of time durations, assign the first set of child rental NFTs to the renter, mint a second set of one or more child rental NFTs for the rentable item for time durations other than the first set of time durations, assign the second set of child rental NFTs to the owner, and burn the rental NFT.

Abstract: A non-fungible token (NFT) game is provided that allows the players to create image NFTs from color pixel NFTs. The NFT game provides the tools for the players to mint different color pixel NFTs with different sizes different shapes, and different colors. The players may search for and may buy different color pixel NFTs. The players may sell the images they create and may buy images created by other players. The game provides a drawing pad and displays at least a subset of the color pixel NFTs that a player owns. The player may generate an image by moving the color pixel NFTs into the drawing pad. The player may mint an image NFT from the color pixel NFTs moved into the drawing pad. After the image NFT is minted, the color pixel NFTs used in drawing the image NFT are burned.

Abstract: Apparatus, systems, and methods a crypto chat social software system can use the user's biological information to ensure the security of the account through a secure encryption method, which is not easy to be cracked, so that the user can fully control the security of his account. Encryption on each data generated by the user's application of social chat software is performed to ensure that only the users themselves can view the application's data and digital assets. The server storage can be decentralized in that al data stored and backed up are encrypted information. Accordingly, users' private data and digital assets cannot be stolen and abused. At the same time, the user's data will not be affected, the user still owns, and only the user owns their private data and digital assets.

Abstract: It is an objective to provide an arrangement for initialising at least one qubit to a thermal state. According to an embodiment, an arrangement for initialising at least one qubit to a thermal state comprises: at least one qubit; a thermal bath structure selectively couplable to the at least one qubit, wherein the selective coupling is controllable using at least one coupling control signal, and wherein an effective temperature of the thermal bath structure is controllable via a temperature control signal; and a control unit configured to: set the effective temperature of the thermal bath structure to a target effective temperature via the temperature control signal; and initialise the at least one qubit to a thermal state by coupling the at least one qubit to the thermal bath structure in the target effective temperature using the at least one coupling control signal.

Abstract: It is an objective to provide an arrangement and a quantum computing system for qubit readout. According to an embodiment, an arrangement for qubit readout includes at least one qubit and a controllable energy relaxation structure comprising at least one junction. The controllable energy relaxation structure is coupled to the at least one qubit, and is configured to absorb, in response to a control signal, at least one photon from the at least one qubit via photon-assisted tunnelling of a charge through the at least one junction. The arrangement also includes a charge storage configured to store the tunnelled charge and a charge sensing structure coupled to the charge storage. The charge sensing structure is configured to provide a readout signal in response to detecting the tunnelled charge in the charge storage.

Abstract: A sleeping system is provided, including an air bladder and a diaphragm pump. The diaphragm pump communicates with the air bladder. The diaphragm pump includes a base, a first inlet, a first outlet, a first noise-eliminating foam, a pump body and a cover. The first inlet is formed on the base. The first outlet is formed on the base. The first noise-eliminating foam is disposed in the base. The cover is connected to the base and covers the pump body, wherein air flow passes through the first inlet into the base and travels through the pump body and the first noise-eliminating foam, and leaves the diaphragm pump through the first outlet to be infused into the air bladder.
