IonQ Has the Most Powerful Quantum Computers With 79 Trapped Ion Qubits and 160 Stored Qubits
Posted by Klaus Baldauf in categories: computing, quantum physics
IonQ just made a presentation on two new trapped ion quantum computers with 160 stored and 79 processing qubits. This is more qubits than the best noisy superconducting quantum computers which is currently the Google 72 Qubit Bristlecone processor.
* IonQ systems are at room temperature
* IonQ manipulates ions with magnets and lasers and have software control on mostly FPGA chips.

Posted by Michael Lance in category: space travel
NASA has offered to give NBA superstar Steph Curry a tour of one of its lunar labs after the Golden State Warriors guard said on a podcast that he doubts humans landed on the moon.
No, really.

Best Bitcoin wallet: Hardware or hosted?
Posted by Philip Raymond in categories: bitcoin, cryptocurrencies
The question asked in the title has been edited from what was asked today at Quora, the Q&A forum at which I participate as expert columnist. The original question was a bit more ambiguous: “Which is better? — a digital bitcoin wallet or a physical one?” I have included the original question, to better distinguish products and terms.
All bitcoin wallets are all digital—even a paper wallet, whether a character string or a QR code. Conversely, an exchange may use “physical” wallets to host client assets, individual application wallets, or they may simply keep records of client assets that are stored, collectively, in their own master wallet. To complicate matters, Bitcoin is never really “stored” by you or an exchange service. It is stored on a public blockchain, where assets and transaction history can be traced through time by anyone. Therefore, all forms of user access are “digital”. What the reader really wants to know is “Which form of access control is better? — custodial or personal?”
Type 1: Custodial Wallets are Managed by a Trusted Party They hold your assets. You view a statement balance—just like a bank account.
