The Stack — April 20, 2026

Today's technology briefing highlights key developments in quantum cryptography, significant industry investments, and advancements in autonomous vehicle technology.

Quantum Cryptography and Infrastructure

Recent advances in quantum computing are pushing major tech companies closer to "Q-Day," a critical point when quantum computers may break current cryptographic systems. Companies are actively transitioning to post-quantum cryptography to safeguard data against future quantum threats. Additionally, the construction of data centers in the US is facing delays due to energy supply issues and local opposition, potentially impacting tech infrastructure expansion.

Industry Movements and Investments

Uber has shifted its strategy towards a more asset-heavy model by investing over $10 billion in autonomous vehicles and related technologies. This includes significant investments in companies like WeRide and Rivian, marking a departure from its previous asset-light approach. Meanwhile, Eclipse Ventures has launched a $1.3 billion fund aimed at incubating startups, including a new autonomous hauler project in San Francisco.

In the realm of electric vehicles, Slate has raised $650 million in a Series C funding round to support the production of affordable pickup trucks by 2026. Glydways, focusing on personal autonomous pods, secured $170 million, and Loop raised $95 million to enhance its AI-driven supply chain solutions.

Autonomous and Electric Vehicles

Waymo is expanding its autonomous vehicle testing to London and has removed its waitlist in Miami and Orlando, indicating growth in its robotaxi services. Additionally, Rivian is partnering with Redwood Materials to implement battery energy storage at its Illinois factory, utilizing second-life battery packs.

Robotics

In robotics, scientists are developing HexSkin, a solid material designed to provide humanoid robots with a sense of touch comparable to human skin. This innovation could enhance the capabilities of robots in various applications, offering seamless coverage over complex surfaces.

These developments underscore the ongoing transformations in the tech and automotive industries, particularly emphasizing the push towards autonomous and electric technologies.
