🕹 Technology Quantum Computing
  1. AI is surging with huge investments and a shift from answering questions to taking action, including efforts to build fully automated researchers, but it also brings real risks like security concerns, harmful chatbot behavior, and deepfakes.
  2. Energy is still the core currency of civilization: disruptions to energy quickly ripple into food and economic costs, and long-term progress depends on energy multiplied by knowledge — energy times information.
  3. Investors and scientists are leaning into big technologies like nuclear fusion, commercial space stations, and quantum computing, even as other industries such as batteries and some electric-vehicle realities face tough economic and practical challenges.

The Q-Day Edition

Why is this interesting? • 1025 implied HN points • 05 Feb 26
🕹 Technology Quantum Computing
  1. Nation-states are quietly collecting huge amounts of encrypted data today that they can’t read now, betting that future quantum computers will let them decrypt it later.
  2. That strategy flips the usual logic: instead of information losing value over time, encrypted data can become more valuable as quantum advances approach.
  3. This reality forces a rethink of security and policy — we need post-quantum encryption and stronger counterintelligence because many current secrets are effectively already compromised even if they remain unreadable today.

Optical Conversion of CMOS <> Superconducting Signals

Tapa’s Substack • 119 implied HN points • 10 Sep 24
🕹 Technology Quantum Computing
  1. There's a new idea to use light to switch superconducting signals with CMOS circuits. This could help in areas like quantum computing and sensors.

@adlrocha - Is N=NP?

@adlrocha Weekly Newsletter • 64 implied HN points • 14 Dec 25
🕹 Technology Quantum Computing
  1. Complexity theory measures how much time and memory algorithms need so we can tell which problems scale feasibly and which become intractable. It separates problems that are merely computable from those that are practically solvable before resources run out.
  2. P contains problems solvable in polynomial time, while NP contains problems whose solutions can be verified quickly even if they seem hard to find. NP-Complete problems are the hardest in NP because every NP problem can be reduced to them, and NP-Hard problems are at least that hard but not necessarily verifiable quickly.
  3. If P = NP, many cryptographic systems would break because one-way functions would no longer exist. At the same time, P = NP would let us solve huge optimization and AI problems exactly and efficiently, radically changing many fields.
